You have the best technical reviews IMO here on youtube, especially with the amount of experience you have, thanks a lot Andrew !! Would love to see your review on the new Aputure products, especially the 600d, it seems so amazing for it's size !
600D will be taken very serious by gaffers. Built in lumin radio, weather proof, and a decent Fresnel mount. They have really listened to gaffers feed back.
Finally someone its taking the time to see the deeper fusións like DMX or using with more accesories. Thanks for taking your time and make it so informative
Totally agree with the last comment 9 months ago! Best technical reviews period of lights I've found! As a professional commercial still photographer of over 20 years you are hands down the best at providing what I want to know about a light used in different scenarios!
Gaffer & Gear Strangely enough I got that at the same time. The Lantern has to be one of the most portable user friendly soft modifiers out there. The combo with the 300X is great for quick set-up location work, mostly my thing. I recently did a mini-promo for a care facility and that was all I took. I could tune the fill to match 6000K natural window light or that horrible ubiquitous fluorescent (I used 4000K). There was more than enough power in this scenario, which was my main worry when I bought the unit. And the footage looks great. Very natural looking skin-tones. I think this combo is my new go-to. My little flat panels deserve a break. Thanks for a great channel.
Wow, the amount of valuable information you fit into your reviews is outstanding. The amount of work that you put into everything and your attention to detail is mind blowing. Thank you so much. 🙏🏾
Love the channel, great reviews which actually talk about features and pros and cons of use, rather than just being a glorified ad with one nitpick like many "not sponsored" ads I see.
I'm so glad I've found your channel! This review was excellent, thank you so much for all the detail you've put into it. I was hoping you'd mention if they're flicker-free for higher frame-rates, but looking through the comments you'd answered this. My dad's a DOP and he's probably tired of me constantly asking him about equipment to my fledgling shooter self (I'm an editor by trade, moving into self-shooting etc. in the last few years). Very happy to have found such a great resource for lighting info!
I am fairly new to "modern" DMX. It all got too confusing for me after LED came out. I've only just got into lumin radio. And that's just using my exalux. So I'm not using artnet or anything like that. So after this whole covid19 thing is over I might hit up some of the larger gaffers in melbourne to talk about big scale DMX.
Best review of this fixture on UA-cam! You covered almost all information needed, great job. Are barn doors can not attach to fresnel? If they can, I didn’t see how they perform… are they any good, when combining with the fresnel attachment, and do they cast multiple shadows in this combination as well ? Thanks👍
Finally an actual, serious, review of this light on UA-cam! I'm wondering, the light doesn't have lumen radio but you're still controlling it wirelessly, what is your setup with the Exalux?
Thanks for your detailed work! How does the brightness of the APUTURE 300d with full CTO compair to the brightness of APUTURE 300x set to the same color temperature? In other words Is the 300d bright enough to use a CTO gel and still be brighter then the 300x?
If you go to the gel manufacturer website they will tell you the light transmission of all of their gels and you can calculate the difference exactly. Generally speaking a daylight LED with a full CTO gel will be a similar brightness to a Bicolor light with similar wattage.
Another great video! I want to buy my first lightmeter and woulde love your thoughts on the best affordable one. I need color temperature and tint too no color tho. Would be great to hear from you
I have no real advise on light meters, it's been so long since I looked into it I think my advise would be outdated. I have a sekonic spectrometer and a UPRtek spectrometer. The sekonic is my go to.
Gaffer & Gear thank you. Have you heard anything about the lumo light and color meter? Since the most affordable sekonic I found that’s able to read temperature costs 1300€ and many youtube reviews praise the lumo but your channel is the one I trust the most. Maybe someone else here has some experience with the lumo?
Ha... just bounced off your 300d II review. Working in lots of corporate environments where I have to match ambient color lighting, this is the solution I'm looking for. Thanks for your attention to detail. Great info. The real question is, can you poke it with a pen?
Thank you so much for this Great video....ist was an eye opener to me personaly! I Wonder if you know which Gobo you used for the background at 21.33 ?
Nice! Thank you so much for your in-depth reviews! You're my personal authority on gear, and I appreciate what you do! Quick question, between the ease of internal bi-color to overall light output, would you recommend the 300x over the Nanlite Forza 300 or Godox VL300? I've been leaning toward the Forza ever since I watched your review, and would love to hear your take.
I'm reluctant to recommend any light over another because it totally depends on your situation. For example I went with the Forza 500's primarily because they run off my block batteries. But that's not a consideration for 95% of people.
@@gaffergear Hello Andrew, Love your stuff. i would like to piggy back on your response concerning Block Batteries. I am currently debating how much to invest in V Mount Batteries, because when I do the math a block battery solution makes more sense, especially when it comes to more powerful lights. Could you do a video on Block Batteries (like the battery made by D&O lighting that dropped from $2000 to $999 and is a 900 WH Battery). I'm interested in which Block Batteries you use and how you use them to get the most power for the most time. I'm also interested in the cost aspect. Thanks!
Just to add something to the battery discussion, I've been using AC inverters. For my forza 500 I use a unit by DeWalt, meant for shop/construction work .... and for small godox and fabric LED Matt's I use small Ryobi 150w inverters.
Hi Mate, Thanks for this review. managed to get one last week and like it more that I thought I would! What high amp V-mounts would you recommend in Australia? the only ones I can find are the Core Neo 150s Batteries form Kayell that are quite expensive. Cheers mate, Dane
I have yet to get a 300b for review, Nanlite are still working in improving it. I think the mains things are the Nanlite is brighter and has a better fresnel attachment. This unit is better build quality and slightly better colour render. Sory for the delay answering, UA-cam notifications magically appeared
Hey Andrew, was circling back on this video because of the announcement of the 600X Pro. With regards to the specific characteristic mentioned at 16:22, do you think the 600X pro will exhibit similar behaviour with the spotlight mount since it has a similar optical blending for the diodes?
I haven't seen how the 600x blends it's emitters yet, but my gut feeling would be yes, unless it is going through some sort of mixing diffusion, but I doubt they would do that would reduce output the light output. I should have a 600x for beta testing soon.
As usual your reviews are very descriptive and technical, I have not been able to find reviews on the Nanlite Litolites 8F and 28F, IF YOU HAVE A CHANCE please take a look at them or on the other side you might consider they are not significative to consider a Review?
I don't know if I would review these, but if you message me with what you would like to know I can run a meter over them when I'm at the distributors next.
Hey Andrew, now that 300X are being used on set and having one myself, I’m realizing that they run very green especially at lower color temperatures, and the CCT accuracy is 300 to 500 kelvin... So I’m wondering, could it be that the unit sent to you was calibrated individually?
Wow! This looks really interesting. Thanks Andrew for the thurough review. Quick question. I am a product photographer/videographer and really need deep focus. Would you suggest the 300D Mkii or the 300X? I shoot stuff raning in size from tattoo needles (macro lens light levels) all the way up to furniture. I also shoot music videos and some short creative narrative stuff, and can see the advantage of having tunable color temperatures. I'm thinking the extra fire power on the 300Dmk2, with some gels might be the way to go. But curious on your opinion. if I contacted you for a rental what would you recommend. I also just got the Aputure 36 degree spotlight based off of your review, and used it for a campaign this week and am LOVING it! Keep up the great work.
Great video as always! I e dwd up buying the 300dII much because of your interview! If you don't mind, I have a question. I've used some cheap gels with the 300DII in the gel holder, but they have always quickly melted. Is that a fire hazard? Do you have any recommendations for some more heat resistant gels? I've looked all over the Internet but not been able to find any reliable information. Thanks for your great work! Love from Stockholm
I have found that dark gels will melt because they absorb more heat, light gels like a CTO tend to last a while, I use Lee, Rosco, and for a cheap alternative I use Chris James. Gels melting is not a fire risk, with the exception of spun (spun fibreglass diffusion)
Sad that flicker test are missing in new reviews, because many lights start to show lines of flicker when shutter is over 1/500 and more common over 1/1000. For high frame rate it is very important. This is why i need to return 300d mk2 in store and get rid of all my aputure lights.
I'll put this back in future reviews. My frequency metre is not working to what I would consider to be trustworthy, even though it has been re-calibrated, but I figure I can do a simple shutter test with a mobile phone, and show if lines appear. That will give some indication, but these lines appear on 1000hz HMI. And they are considered flicker free. The technology has changed for flicker free LEDs. They no longer need super high speeds, but can run at slower speeds with a much smaller gap between pulses. So with the old technology you needed at least 24Khz to be considered flicker free, (that was a SMPTE standard), but with the new tech you get the same result at 14Khz. With reviews recently I've left this information out if the light is more flicker free than a 1000hz HMI, which these were. I have used these for high speed filming with no flicker, but only at 700 FPS on the Phantom.
Hi GooDween, generally the Aputures are good with high-speed shooting scenarios. I've personally tried them on sets up to 1000FPS on the Phantom Flex Cameras without issues. Even on the newer Novas, there's a Frequency Selection mode to compensate for different high-speed situations. To be honest, we don't hear about the lights flickering often so if you're experiencing it, there's a chance that your unit may be faulty. Can I suggest we take a look at it through our dealers perhaps, can you drop us a mail at cs@aputure.com and cc marketing.asia@aputure.com ? I'll help to take a look.
@@jlimproductions9411 I have already sell or return to store all aputure lights that i had, i've tried rma them and aputure said that they fixed my lights, but they not. I can't imagine how you could shoot with 1000fps with them, because all aputure lights that i saw have thin flicker stripes all over the screen even with 1/1000 shutter.
If you were using this unit for outdoor stand-ups (cheap HMI), wouldn't using the 2X fresnel attachment get back some of the output loss of the bi-color unit?
Hey Andrew, I had bought two 300x a few days ago and on my first shoot I noticed them beeing very greenish on 5600K. I had to gel them down by a quarter minus green. Back home I wanted to meassure them, they where between a quarter magenta and a quarter pink off depending on the color, the intensity and the runtime (heat) I don`t know, but that`s not really usable for me. You got any Idead how to handle this? Ah... I wanted to do some other readings too, but I killed one by touching the stand and probably got an ESD discharge trough the unit. I hope Aputure does repair that under warranty
Something is not right. The Aputure team will sort you out. I would jump on a Facebook user group if your supplier is not helpful. The admins are very good on those pages.
Great video but this light lost me with the shadowing. If you get a chance perhaps look at this light. Intellytech X100 its also bi colour but has a built in Fresnel lens.
I don't do 1m because a lot manufacturers are making their reflectors to give a huge reading (hot spot) at 1m so they can put a impressive high lux or Foot Candle figure on their marketing. My experience from years of testing is be suspicious of manufacturers that have no photometric data past 1m. And don't trust a manufacturer who only has readings at 50cm.
Please do the test bear bulb at 1m. We are also not interested in the reflector readout. That’s why we come here. It’s actually deceptive - and really puts me off. Thanks for your help though. Bare bulb at 1m is what we need because this is how we can honestly compare intensity with other lights.
