Dude! 6 years later and you’ve still got the best vid on how to do this. This is the 5th vid I’ve watched on this, and the 1st ont that made sense! Thank you!
I’m about to do this project in my basement and so I’ve viewed just about every video on retrofitting these lights. By far, you have done the absolutely best job of explaining the wiring setup for the dual ended bulbs. THANK YOU!!!
Thanks for the video explaining the difference betweem single sided and double sided LED lights. I watched four other videos and wired it for double sided when I had bought single sided. You were the only one to explain the difference. I was about to call an electrician. You saved me big bucks.
This is by far the best video guide I've found to rewire our shop lights, we had 4 bulb 1 balast lights and no one explained this better than you. Also one thing I didn't know was about the dual or single ends, I had to go check and my bulbs needed power on both ends. Thank you thank you thank you and not having music playing while you're talking.
Much better quality than many of the do-it-yourself efforts on UA-cam. Complete and accurate. Some of the other ones are incomplete (covering only one style of wiring.)
@@ceecee8757 yeah, where are all the ladies retro fitting their flourecent lights to LED ? Can't be harder than cooking T--giving dinner for a family, huh? Ladies need manual skills as much as anyone in this day and age, in my opinion.
Greg,. Just bought 8 LED bulb tubes for my long suffering shop lighting needs. Paid under $60 for the lot. Color and lumens, etc is acceptable. Feit is the brand they had. Seem to be double ended, but it didn't say as far as I can tell. Wired them up as single sided and they didn't work, so more wire will be used. Hope they work as well as other folks LED convertions do. Yours is a good tutorial, so thanks my friend. Bob. Happy New Year
Great job young man. Keeping it simple and to the point. Your communication skills and very good. I have five fluorescent fixtures flush mounted and will leave them in place to remove ballast and do the wiring on a ladder. Too much work for me to tear them all down just to rewire per your excellent video. Thanks. ...and yes, I will turn off the circuit breaker and double check with meter.
i know its almost 4 years later, but after half a dozen videos and websites, this video finally got me to figure this out! thank you! im an idiot when it comes to home improvement stuff and being that my wires were never the same color as what everyone else said (I HAVE NO YELLOWS!!!) but your explanation helped me. thanks again!
juggnuttz. Here's what I did to "convert" different colored wires to show neutrals -- spray paint the last 3 or 4 inches of the wires with white paint on each end before stripping. Then place them in your 'stones like normal
Great Explanation - most other explanations are not clear as to why they connected it the way the did - meaning it is clear now how to connect single ended vs. Two sided. Thanks!
Just built the LED light. Works great lights up the 125 nice. Should look really good after I add the Black Diamond sand to it, a few plants and my old tank will be my new adventure. Thannks
Thanks for step by step instructions.I was able to convert my bathroom light that has failing ballast.Ordered Sunco led lights from Walmart website which is much cheaper than Amazon.Needless to say my bathroom now is more brighter than before.👍👍
Hey, thanks a ton ton ton !! I watched A lot of like videos, no one ever said there was a reason for wiring it differently, so when given a choice who would wire it one sided .. and is which what Ive been doing and tripping garage breakers... Diagram helped a lot to!
Great video .. only suggestion I have is for safety 🦺.. when we convert to l.e.d. bulbs take a permanent market & write ( led only ) or if it has use sticker that comes with bulbs. Only reason for that is if bulb goes out & next person tries to install a flurescent bulb it will explode/pop & burn tombstone up.
This video was a ton of help. I tried to do this on a fixture with shunted tombstones and couldn't figure out why it wasn't working. Now I know. Thanks.
Great video! Unfortunately the Sunco mfr does not have double-ended bulbs now. They only sell single-ended bulbs. I replaced a bunch of fluorescent bulbs with double-ended ones and now if any burn out i will have to rewire fixture for single-ended and mark it as such. I would prefer if they were all the same.
Nice job Greg... just a note on the terminology... the L stands for line not load. The bulb is actually the load but in AC electrical terms, the L is the hot side or line and the N is the neutral or common side. You did a great job on the video...in a lot of instructional videos, the host is all talk and no action. Sometimes I just want to toss my iPad across the room. You got to the point and kept it interesting. Thank you!
Great video! I saved it as a tutorial for an upcoming four lamp kitchen light LED project. Any thoughts on the $6.97 shop light LED bulbs from Harbor Freight?
Great video Greg! I'll have to do this project on my older 48" shop light! I appreciate the tutorial it's going be very helpful! I'll post a video of me doing what you just did but I'll give you credit of course in the video and in the description!! Thank again!! :P
I saw your video, because I want to try switching over from T8 to LED lights for my houseplants, but I have a problem and that is most of my lamps don't have visible screws to take them apart to find the ballast to remove. The model number on one of them is .234SLESW, rapid start, and the "tombstones" seem to be sealed in as a single plastic unit on each end of the lamp. (these are what I find locally available at Menards.) The bulbs I'm trying to use are GT-Lite T8 grow bulbs. The claim on the box is that they can retrofit a number of older fixtures except "electric chip" though the directions on what works and what doesn't is a bit lacking. It was only in a single place that I found the disclaimer about electric chip ballasts. That said, I have one fixture like the one you used that I can attempt this project upon when I feel ready to tackle it. I haven't removed the ballast and the retrofitted LED works as advertised. The other lamps that I described, do NOT work with the LED lights, even though they are listed on the bulb's box as compatable aka "rapid start", "instant start.". One smoldered and sparked. The other just popped and then shut off. The remaining fixtures I haven't tried. Are these just sort of out of luck, disposable once they quit being useful with old fluorescent lights, or can they be made compatible with LED bulbs?
Interesting that one only needs one side and using the proper bulb. "They" sales people selling the bulbs make it sound so easy to install. Not one sales person mentioned Shunted or non shunted lamps.....perhaps they do not know, but they should. Great video thumbs up thanks!
I have an old neon light fixture using the fat neon tubes and ballast. The ballast is faulty, and I want to convert to T8. Do all the tombstones have to be replaced to accommodate the skinnier T8, or will the pins still work in the older tombstones? THUMBS UP!!
we have got clear led tubes 4ft,non shunted,removed the led strips an inserted 3 -150 watt led full spec strips,i used A LED DRIVER TOO,IT WORKED GREAT DID A 4X4 ROOM ON VEG TO FLOWER,4 LED TUBES,RED,BLU,WHITE, TOP SHELF ,HIGH INTENSITY LED STRIPS,NON SHUNTED
Hey Grey.. I did test the t8 philps led with shunted lampholder since the new casing bought is thinner and used only 1 wire at both ends.. Nothing really happened.. Then, i tested with normal Non shunted and walla it works.. I think the casing meant for double sided led.. But the label on the philps says other way around.. Glad the led wasn't damaged..
Very nice! I also just found a 20-Pack T8 LED Light Tube, 4FT, 18W (40W Replacement), 5000K (Day Light), 2400lm, Frosted Cover, Dual-End & Single-End Powered, Works with/without ballast, Shatterproof, UL & DLC. It’s worked out well for me.
Currently, my kitchen using 6 T8 Florescent Lights / 3 ballast or TWO florescent per ONE Ballast. Is it possible to replace only ONE PAIR with LED and the remaining TWO Florescent will remain connected, All 3 Ballasts powered by ONE SINGLE wall switch. Will the OLD Florescent Lights affect the circuitry of the LED Light Tube. The reason I'm converting only ONE was because the existing ballast of the florescent was DEAD.
Ok so each tombstone needs 2 wires coming out and all 4wires on side to to the black and all 4 on the other side go to the white wire .... so if one side only had 2 wires one on each tombstone that wont work will it and yes there the non sockets
Awesome demo Greg. If you do a followup could you watch out for the colorization of the fish, watch for a temp from them, and maybe put some plants under them to see how the do? Thanks! :)
I have LED bulbs by ge T8 replacement. I have T12s. So I checked for shunting. All 4 tombstones are Non-shunted. I was able to take off the back of the tombstones without damaging to physically verify. Not knowing if the New T8 LED bulbs are single or double ended bulbs. I took a meter to it and Checked for continuity. On both ends I have checked for ohm values. I get 12-13ohms on both ends. When I take an ohm reading from end-to-end I get an open circuit. So how would I wire it up these bulbs? Do I put a black and white at each end of the light bulbs?
Nice very informative.. I'm just wondering.. If it is dual sided led, can it be used with shunted lampholder.. Because one end is live and the other is neutral.. One more thing.. What if the led is one sided input with the label L & N at the end.. Can it be used with two sided wiring? Will it work? I have a philips led T8 ecofit.. There's a label about the wiring diagram.. One is for the 1 sided wiring and the other with 2 sided wiring for live & neutral at one end of another..
Hi, sir, I really like the video you shot. Could you help us take a video of the installation of our brand's 4-foot led bulb? Looking forward to your reply.
It looks like you could use shunted for you double sided diagram, instead of running two wires into one end, because you will have power to both pins with one wire. You would short the single side light with shunted though. Thanks for the video
If you use a small nail, saftey pin or needle, you can remove the wires from the tombstones in order to bridge them together and shunt them using short pieces of wire. This cuts down on the number of wires in the wire nuts. Instead of four wires, you have one connecting to the hot or neutral.
I've purchased a Phillips UniveralFit T12 replacement light tube. On the packaging it does not tell me if it is single ended or double ended. How can I tell? Also, how can I tell if the light tube can be used without a ballast or not if the packaging does not specify?
You show non-shunted tombstones as having (L, line and N neutral) at 4:40 .then when you convert the fixture wires you join them together (two blue and two yellow).Would this not be shorting supply Line and Neutral?
You can do double-ended power bulbs with either shunted or non-shunted tombstones. These happen to be non-shunted. For single-ended power bulbs, the tombstone MUST be non-shunted. For the blue and yellow wire, these were probably only differentiated for where they connect inside the ballast and why that is, I can only guess. For the re-wire, it doesn't matter, because we then know all blue/yellow will be carrying Load to one side of the bulbs, and all red/maroon will be carrying Neutral from the other side. Edit: To clarify why the color of the yellow/blue/red/maroon colors doesn't matter, the colors probably had something to do with the ballast's circuitry, but since the ballast is no longer being used, the only important thing about those wires is that they carry Load to one side of the bulbs and Neutral from the other. It might be that there's a PCB inside the ballast that monitors each connection separately for some kind of error handler for safety and each color needs to go to a specific node on the PCB, or something even simpler, like making it easier for the person assembling the ballast/fixture to paint-by-numbers and just make connections in a certain order by color. I have no idea what it looks like inside a ballast or the details of how it works, so I can only guess.
Nice tutorial but with one exception. If your fluorescent fixture has shunted sockets just use them and save your self a lot of trouble and expense. Its really no trouble to simply connect the wires (or wire) from one end to your hot wire (usually black). Connect the wires (or wire) from the other end to the neutral (white) wire. That's it. You don't have to buy new sockets. Just remember to buy double-ended LED tubes.
I have the same lamps, model 1233, and wired them exactly as you have demonstrated, but the bulbs do not light up. I know the bulbs are good because I've tested them. Any thoughts?
i have a t-12 led 4ft shop light, it has reg white light,is thier any easy way to make it full spectrum for plants,?i use a 8 bulb t-5 to veg up ,an a 4bulb 2ft t-5 to clone an start seedlings,would the flour fixture conversion work the same on t-5s,thks
Funny that you said that nobody uses t12 anymore...I was at a Home Depot where I live, and a sales person told me that nobody uses t8 anymore when I was looking for a t8 version of a fixture lol..
It's strange that they have not standardized the wiring for LED tubes - some a re single sided wires with a dead end and the others have powers on both end with one side hot and the other is neutral. Shouldn't you have tested the old tombstones to see if they were shunted or not? In an a very old fluorescent with a starter are they usually shunted or not?
Dude! 6 years later and you’ve still got the best vid on how to do this. This is the 5th vid I’ve watched on this, and the 1st ont that made sense! Thank you!

I am such a newbie with electrical projects but was able to follow along and alas it worked! Thanks Greg!
Just used your guide to rewire an aquarium light for our new LED light, went flawlessly, thanks for the video!
I'm pretty sure you can use shunted tombstones for double ended bulb as its all the same wire going in
Your vid is the best explanation I've seen on converting fluorescent to LED
Great Explanation - most other explanations are not clear as to why they connected it the way the did - meaning it is clear now how to connect single ended vs. Two sided. Thanks!
Excellent job, you are good teacher!!
Thank you for the easy walk thru. Followed your video step by step and my lights are up and running!
Thanks man! Watched a lot of videos about this. You explained everything very well. Best video on this.
Excellent video. Some are telling people to switch out tombstones instead of deciding the type of bulb needed shunted or non. Easy instructions
Just built the LED light. Works great lights up the 125 nice. Should look really good after I add the Black Diamond sand to it, a few plants and my old tank will be my new adventure.

Great video very helpful. Your video is best .
I saw some videos and you explained the best and also the painting is very understandable. Thanks
Best video on converting these fixtures, thanks
Thank you for taking the time to video and share with us your experience. Very helpful. 😀
Very much helpful video, many thanks!!

I had received the Sunco brand bulbs and followed your instructions and installed ten lights. They all work very bright. Thanks
The most important thing is the connection type. Saw many videos on one side connection but I had 2 side connection bulbs. Thanks!
Great video. Thanks much, this could have been an Electro Boom moment! 😷
Great video😊

I have a bulbs the can be content to just one end or both ends
Thank you for the detailed instructions. It was very easy to understand. I think I am now comfortable to try it.
You're statement to "not use" the shunted tombstone is great. I've seen other videos that mention using shunted tombstones. Confusing.
How do you put a pull chain on that light to shut it off
Hey Grey.. I did test the t8 philps led with shunted lampholder since the new casing bought is thinner and used only 1 wire at both ends.. Nothing really happened.. Then, i tested with normal Non shunted and walla it works.. I think the casing meant for double sided led.. But the label on the philps says other way around.. Glad the led wasn't damaged..

Great video. But isn’t L for Line ?
Is the t-12 brighter then the t-8,I have a large shop. Thanks
Currently, my kitchen using 6 T8 Florescent Lights / 3 ballast or TWO florescent per ONE Ballast. Is it possible to replace only ONE PAIR with LED and the remaining TWO Florescent will remain connected, All 3 Ballasts powered by ONE SINGLE wall switch.
Will the OLD Florescent Lights affect the circuitry of the LED Light Tube.
The reason I'm converting only ONE was because the existing ballast of the florescent was DEAD.
thanks, happy 2019, very clear demonstration, solved my problem
Ok so each tombstone needs 2 wires coming out and all 4wires on side to to the black and all 4 on the other side go to the white wire .... so if one side only had 2 wires one on each tombstone that wont work will it and yes there the non sockets
You can use shunted stones for double ended bulbs as its all the same wire delivering to an end.
This is amazing video. Thanks for the details.
Awesome demo Greg. If you do a followup could you watch out for the colorization of the fish, watch for a temp from them, and maybe put some plants under them to see how the do? Thanks! :)
Your just so knowledgeable and helpful .... great video Greg 🤗🤗
Thanks PB!
I have LED bulbs by ge T8 replacement. I have T12s. So I checked for shunting. All 4 tombstones are Non-shunted. I was able to take off the back of the tombstones without damaging to physically verify. Not knowing if the New T8 LED bulbs are single or double ended bulbs. I took a meter to it and Checked for continuity. On both ends I have checked for ohm values. I get 12-13ohms on both ends. When I take an ohm reading from end-to-end I get an open circuit. So how would I wire it up these bulbs? Do I put a black and white at each end of the light bulbs?
It would be nice if you did a video for single ended led tube.

Excellent video and very educational, you should be a teacher man. hehehe. Thanks and I am going to fix my led lights in the garage now
does it matter which side of the fixture you make the hot? left or right, and does it matter which way you put the bulbs in?
Hi, sir, I really like the video you shot. Could you help us take a video of the installation of our brand's 4-foot led bulb? Looking forward to your reply.

Looks like shunted would work fine for a double sided bulb.
I FOUND IT ! THE BEST
Your video was the easiest one I understood to date. My question is not light related, what’s the humidity level there in the “Fish” room? 😳
nice video Greg, thanks
Great help brother thank you!!! I saw a bunch of tutorials with electricians and sounds like there speaking Greek
i have a t-12 led 4ft shop light, it has reg white light,is thier any easy way to make it full spectrum for plants,?i use a 8 bulb t-5 to veg up ,an a 4bulb 2ft t-5 to clone an start seedlings,would the flour fixture conversion work the same on t-5s,thks

Great instructions. Lonely orange fish makes me sad.
It would be wise to check each "Tombstone" connector with an OHM meter to insure you don't have shunted connectors!
The bulb is the load.
The black conductor is the line
