Well I have been trying to get to the aquaman project but I’ve had so many issues with it. First and foremost! It has been crazy cold and I haven’t been able to get my small shed warmed up with my tiny propane heater. So I’m building one to solve all my problems out of scraps and I won’t have to freeze anymore!
why does it even have a flicker? shouldn't it just be "on" if it's running DC? I guess I don't know enough about electronics. Would it have no flicker if the DC came from a battery instead of synthetically converted from AC?
oh, yeah, a quick google search tells me flicker in LED's all come from when AC power is the source. Do your battery based LED's have a flicker? I don't know jack about photography and lights, but I'm very curious.
haha, someone got a little happy on Amazon with the "cpu" grease images-na.ssl-images-amazon.com/images/I/91ryHlCGy%2BL._SL1500_.jpg Might I suggest long zip ties to hold the fan on to the heat sinc? the heat should be low enough that the zip ties should live for a few years before degrading from being warm. or maybe fence wire, might be better
If you watch some reviews of other diy lights you will notice that they flicker when dimmed. This is because power adjustment is finiky and they actually regulate brightness at lower percentages (sub 20%) by faking out your eye. Another culprit could be a low quality ac adapter which is probably the issue in this video.
I think the biggest issue is the LED used. For $100 you could have gotten a CREE and I think that would have removed the color shift. The 120d uses Cree. I don't think you can expect high enough quality out of anything under 95+CRI.
@@loukask.9111 CREE is a manufacturer of led cob chips like the one used in the video and the one in the 120dmk1. As for the color shift, I have not had good luck with anything below 95cri and in fact I try to keep all my lights 97cri or above because I have had issues with Kelvin temperatures matching with lights below 97cri.
@Marcin Kranc I was assuming it was a 100w cob. Marcin I clicked on your link and Google asked me if I wanted to download the PDF........ Again...... I realized that I spend too much time researching this stuff.
@@JohnKlosner I appreciate it. One day, I'll be 100 years old, but finally have the perfect studio and then i'll be able to record some good content. haha :)

Well last time i asked you you ignored me but im gonna take a poop and easy diahrea
Great DIY Project for studio or camera shooting
Pretty cool man. I need new lights. lol
This had some great info.
My dude! Thanks for watching :) what insane project are you currently working on?

I can’t wait. I always love your videos!
Thanks man!

oh, great video btw! forgot to say that at the start

@@JohnKlosner that makes sense

what does that mean? can you explain cree and the other stuff you mentioned to me?

@Marcin Kranc Oh I own several dope lights as well, Aputure 300d/120d/120t/tri-8c, Lupo superpanel dual color / superpanel full color 30, few others.
