You just upgraded to what I purchased first. Only difference, I bought mine for under $900 and works awesome. 1 Minute exposure time for 150 mesh screens.
I use the Anthem Screen Printing Exposure Calculator that starts at 18 seconds times 10 tries, giving a window of up to 3 minutes at free cost.
Hey Lee I’m a screen printer in Atlanta and I have regained my motivation to print again since finding your channel. Thanks brother. Keep it going!! 🤙🏽
Happy to hear that man! 🤘🏻
Hi! It is really a very perfect updated LED Exposure Unit!
By the way, please feel free to get back to us, if you will need Adjustable Smart High Power High Voltage (LED) UV Lamp EPS Ballasts, reference at www.uvballastsupplying.com. Thanks
@@PaperPackingMachines Yeah, really perfect LED Exposure Unit!
Needing out can be a good thing. Can't wait to see what comes out with the new exposure unit 🤙🏼
Thanks for making this video. I ordered one at the end of December and it's supposed to be delivered this week. Now I really can't wait! Good shit bro. 🔥
Hey Lee i'm all the way in the Caribbean from Trinidad. You are definitely an inspiration. I've been doing strictly HTV for some time now and finally getting into Screen Printing. Your videos have been so helpful. Love your channel 🙏🏾
I love how you break everything down. Your video are very helpful for a beginner like myself
Hell ya I'm happy to hear that
Great info as always! Thanks for being the perfectionist you are👍
Them some bright lights!! Hopefully you get everything worked out perfect!!
It's been a few weeks now and it's working so good 🤘🏻
I appreciate the info and time man!!
Sweet new stuff love it 😍 taking it up another notch 👍😁
Hey bro! I’ve been following you for the last year since you’ve opened you shop. Keep up the great work bro! I love your channel and informative and entertaining it is!
Thanks dude 👊🏻
I binge watch all your video in one day
I like nerding out on screen printing too... my favorite process is CMYK ✌👌🙌 love screen printing like a printer
I use the same unit at my work. It's super good and i have never had any problems with it... You'll enjoy it! All the best
Loving it so far. Big difference from the old unit

Awesome videos. You have definitely helped me in my foray into printing.
Thanks man, happy to hear 🤘🏻
New stuff is just cool anyway... the smell when you open the box...especially Electrical stuff...it has that certain smell...can't describe it ...it just makes me happy inside 😛
But....far too expensive for me to even consider buying new..or used...I'm making one like Waldo's...1000 watt led light...microwave timer...and some other STUFF 😜 Love the video
You are still our hero!!!
Kinda enjoy the last 2 minutes of the video and seeing the trials and behind the scenes of things not in the video. Not sure if it makes sense, but it makes it more relatable, because we can all get excited over getting a good shot, or making mistakes like dragging an exposure unit down some stairs.
I've been throwing some of that stuff in the last few videos, I'm really starting to enjoy it. I've always tried to keep it in the main story but it never seems to work and get cut, now I have a spot for it
love the new content keep being great brother this is awesome still htv one day I will be on your level!!!
It took six people to carry my exposure unit down the garden to my shed...its a beast. Single light source.
I'd be stupid enough to try 😂
Thanks for the information.
Looks like you got your workout in 💪 good shit man! I know some people getting prints done. I'm going to tell them about your shop
Hell ya thanks man 🤘🏻
Great exposure time guesses, how much snow did you get in Winnipeg, I got about 13” in east Selkirk
I’m loving your channel
Thanks 🤘🏻
Wow! I’m using a small exposer box from ryonet and I’ve starting to get unfinished cures on the inside of my screens. It’s driving me crazy. Plus my flash times are in the 3 to 4 minutes with this small 2 bulb box. I’m really not ready to make that jump but with my business really taking off, I might need to figure out this new box purchase. Great video!
You won't regret it!
Def should do a “behind the print” series
Haha.....awesome...and Wheelie!! Lol...nice job tho man and omg your quality check!! That’s paying attention to detail! But as everything else on this channel....and happy the experience is paying off...first couple try’s is no easy feet
this should be interesting! EDIT: - built my own LED unit, typical exposure time is 33 seconds. half-tones work out decently on the first try. I also struggle with super thin lines, and I just know it is the limit of what I can do. great video Lee.
That's just an inherent problem when using films, they'll always have their limitations. CTS systems are when you can pull off literally anything 🤘🏻
Mind sharing which led you used on your diy unit??
Just for fun - try some LED specific formulated emulsions to how they compare to what you are using. I'd love to see how they compare.
I'll have to look into that
Did you finally figure out exposure times for each mesh?...
What do you recommend for preparing films with Photoshop?...
Good stuff Lee. Keep in mind that LED isn’t strong enough to fully penetrate emulsions for long waterbased runs either, and that the multiple strips maybe be contributing to the undercutting more than just the film. Fastest emulsion, and thinner EOM may help reduce it! 👍🏼
Always post exposing in the sun is the best bet. And limiting the amount of water that you introduce during the rinse stage helps too.
Oak City Creative Arts Can’t always bet on the sun being out though, or it not being -30C outside haha.
Cory @ Floodway Print Co. you can always put it back on your exposure unit for a minute of two. But our backup plan is a bit more unconventional.
We have a grow house with a bun rack inside. We turn on the UV’s and re-expose 10 at a time until ready for setup.
Hey Lee, I've been watching and learning from your channel! Definitely gives me the motivation to succeed! On your new LED exposure, can you tell me what tubes are in it? Model or manufacturer of the bulb? I want to convert my dinosaur to LED. Thank you for the informative videos!
Lee your Chanel is awesome , I got a question how did your positive films
That thing is awesome bro! Btw, I've been thinking about getting into screen printing, your videos are definitely helpful but do you know if there is a screen printing kit that I can buy which I can use in a small home setting? Thanks again brother, readings from Toronto!
Hey Lee...I have the older fluorescent one you had...can I ask how often you changed the bulbs..thx
are those white mesh screens? i'd suggest trying it with dyed mesh on the same artwork see if it would have a different result. LED tends to travel down the white mesh almost like ffiber optic make those tiny spots impossibel to wash out.
Try 15secs to get these hair-like fine lines. Also make emulsion as thin as possible by doing coat-coat-scrape-scrape (I'm using Saati TExTIL PV) . I've built my own 395nm 300-UVLED 8 rows of LED strips, 5cm distance in between, can definitely make hairline details even without vacuum.
Also, that much pressure causes jagged details like @10:20, or is it due to the positive you used? Use gentler sprayer, and you'll see the difference. You're inspirational LS38! Hero fosho! Shop is fukin A!!!
That slight bit of jagged stuff is in the positive too. 15 secs would be far too low on this unit even with a super thin coat, 25 secs was really the limit before it was far too underexposed.
@@leestuart38 I see, one factor could be distance of the glass from the led strip. I got mine around 5 inches, where beam is not too spread out, not too focused - just the sweet spot. The UV LEDs used could be a factor as well, and the emulsion used. I start to lose fine halftone dots at around 40-60secs, but generally cooks 12seconds - like perfectly. Anyway, that's a sweet box right there! #38squad
@@leestuart38 Bro, can you try printing out hairlines in Rich Black (C60 M40 Y40 K100) on a Epson Matte (or equivalent) + High quality, and print it out straight out of AI (not using Accurip) (Also must be in CMYK color mode). The blocking ink lesser than this can be be prone to UV penetration. (RGB black is too thin at this UV level of play. Haha)
Mr Lee stuAr my LED 100watts upside down 1ft the distance of rhe screen emulsion image what time of the exposure need it. Thnx
Ryonet's top sales representative
If only it came with the paycheck 😂. I'm just a guy giving an honest opinion on a product, I'd do the same thing no matter the brand name
@@leestuart38 we have no reason to doubt
Hey Lee, have you dialled in your dryer with a donut probe yet? I recently picked one up and was shocked to see the temp difference between it and the laser gun. Crazy. I made some significant changes. Might make for an interesting episode. Greetings from Newfoundland!
i’m having so much difficulty with finding the right amount of exposure, can someone help!!
i’m currently just using a stand a portable light i received with my screen printing kit.
are you still shooting everything with your canon ?
You can just convert the old unit to LED and save a TON of money, the conversion is super simple.
Hi there! Just found your channel and I really enjoy your content! very well done! Im a military veteran and active duty spouse with some past experience in low-tec screen printing, and i have a question for ya - My local military base is having issues with the guy who screen prints the shirts for base personnel and they want to find a new printer soon. What kind of set up would you recommend if I take this on? They need around 250 shirts every week or so. One or two designs on short sleeves, long sleeves, hoodies, crew neck sweaters, and sometimes child sizes. The art work for these are done by military personnel, but will always need some tweaking to make them screen printable. The guy they have now hires a local tattoo artist to "fix" the original art for him. Any info would be greatly appreciated!
hey Lee i have a quick question why would my unit not vaccum correctly?
You’re like the Alton Brown of Screen Printing
Shade tree!!
wow!
I had the same unit you did and am to upgrade to the LED as well in a month. I always have that problem of emulsion not washing off the ink side of the screen and leaving that film. Does this LED unit stop that since it burns through all the emulsion? Also, how did you get that excess emulsion/film off when it happened? I'd normally have to re-degrease the screen after drying it to get rid of it. Please let me know, thanks! Congrats on the upgrade BTW.
This sound like over-exposure or not using enough water pressure when rinsing. It's a delicate balance.
Different printers will give you different tips. But don;t be afraid to take your clean hands and "massage" the emulsion out of the stencil if need be.
Because if your film can't hold up to the skin on your hands, then it definitely won't hold up to the squeegee.
@@oakcitycreativearts Thanks. You're right about the balance. I do use my fingers to rub the emulsion off, but I probably could use more water pressure. I use a garden hose on "shower" rather than a pressure washer.
I've tried black light LED and I cannot burn halftones at all . No matter what the time I use I am under and over exposed all at the same time
The evil laugh though lmaooooo
😂😂😂
You should replace your fluorescent bulbs with UV bulbs, and analyze the difference.
Hello !! Was this upgrade good? What can you tell me about these new Leds? Photopolymer emulsion reveal well? Thanks
It's 100% worth upgrading over the fluorescent tube version. Photopolymer does better but still not amazing, the fine details still get over exposure. But I've been experimenting with some things to fix that
@@leestuart38 Why don't you use a single 365Nm LEV UV source?
how much would you sell your old one for
Total new person here - what is the little slip of paper? film? that you held up and told us to make sure we were using it? Is this something that works as an exposure gauge?
You got it right, thats an exposure calculator
@@leestuart38 I have seen a few of these and used one which involved multiple exposures to work out the time but this looks like a single exposure type. Do you have any links to more info about this type? Google isn't being that helpful today.
something just popped into mind. you can buy LED lights that go into fluorescent sockets and they look just like the ones in your new cabinet. im wondering how that would work.
kevin wallis yep! lots of people have converted fluorescent units this way. Just gotta make sure you find the right bulbs.
@@CoryFloodwayPrintCo I sell a lot of antiques out of a space I rent, and they changed out all the bulbs in the 4 ft fixtures to LED. No ballast required. Directly wired to the power.
Just remember not all LED's are created equal, having a UV source on the proper NM spectrum is everything
You should stick with Ryonet LEDs for bulbs. You might pay more but you can bet your A** they're gonna be better than anything else you gonna buy
expmofo stewmoo FREE SPEECH T'S no need to bet, just check the wavelength.
What's the link for the exposure unit and where can I buy a good printer?
The link is in the description under my print gear. You can get everything you need there 🤘🏻
dammit! why'd you have to pop out a video with this unit, I had it in my cart for the past week debating whether I should upgrade to it or not. looking like I'm sold at the moment. god my wallets gonna hurt
Why not use exposure calculator for single screen frame
Takes more than one to get the times perfectly dialed
Hey! This has very little to do with LED Upgrade, but what size squeegees do you use most often?
15", 12", and 6" are the daily's
@@leestuart38 thanks man!!
What is the most preferred printer to print film positives?
You want a printer that's capable of printing in separations. Epson printers are the most preferred it seems
Lee Stuart oh this is a perfect answer! Epson printer that handles separations, I will begin researching ! Thanks a bunch Lee! Always looking forward to your uploads!
which emulsion should i use with the 50watt uv if im using plastisol ?
Stick with a dual cure emulsion like baselayr long lasting. There's a lot more flexibility with exposure times and light sources
@@leestuart38 thankyou !
What printer do you use for your transparencies
Epson p400
Where did u get that screen storage?
It's a drying cabinet, ryonet makes it 👌🏻
hello, what printer do you use to print the positives?
Epson P400
@@leestuart38 thank you
Can I know more about this
Awesome shit now i want that machine. You can donate your old one to me lol. Good shit like always !
It's definitely worth a look 🤘🏻
🤘💀🤘
excellent I love your videos more, ordered in your work Someday with Spanish subtitles more Latin followers greetings from Nicaragua
If there's one person I want to see outtakes from it's Lee Stuart. I can't stand those who make fake outtakes, whether on YT or in music
Oh man I can name so many that have fake outtakes, it's ridiculous. I'd kick my own ass if I ever even thought of doing that
Can I get your old exposure unit
Save your old exposure unit and use that as a film registration unit instead!
That's exactly the plan 🙌🏻
💯💯💯💯💯💯
I have the Sun in Ghana. Free exposure unit manufactured by God. Didn't pay a single dollar for it.
😁 my brother man ✌
Nice video, but actually it appears all they did was change out the florescent bulbs and install UV LED tube light bulbs. And you don't need any new ballast, you actually have to disconnect any ballast or started to use these builds. The description says: The LED bulbs MUST be directly wired to the 120V AC Power! Please disconnect Ballast (& Starter if there is any) before plugging in the bulb.
So, most likely, you could install these new UV LED bulbs in your old exposure uint yourself if you are handy? The vacuum unit and timer would work without modification, see the wiring instructions in the Amazon link.

let me get that old one haha
I'll be keeping that one and turning it into a light table
if only you had a 320 pound angry german customer service guy to help you with lifting stuff ;)
lmfao
thank Lee for everything! you inspire us: intagram @prophetoutfitters you make screen printing cool!
Always cool to hear that 🙌🏻
Mess no
You ain’t even share where you got the unit, but want me to watch YOU rumbling around???
No 👎🏾👎🏾
Lol wow, stupidity at its finest right here. The brand, the model and who sent it are only mentioned about 20-30 times
