    Please share the power per board of your build and the intended coverage area.:mrgreen:

    Just using them around the house which was my original plan for them after I had my fun, if I remember right I only had one die and just took it to home depot and they swapped it out,memories lol.

    I'm running them in series with a HLG-185H-1050B, I'll have 3 bars with 3 boards each to cover a 5x5 or a little more.

    Test fire, 180 watts at the wall. I have two bars done and ran short on screws for the third,one bar has HSUSA heatsinks and the other two have the slate 2 singles.

    Actually inverse square law does not apply when using optics and reflectors to focus the light. Are you guys not aware of that?

    It still does, but it applies differently based on the optics involved.

    No it really doesn't - a different mathematic function applies, based on the optic used.

    Sorry for somewhat noobie questions.

    Each board can do how much possible watts?
    What watts do you run each single board at?
    What is the max watts you can push with 3 boards and the heatsinks you have safely?
    How much did it cost to make this?

    Over a 4x8 how many of these lights that you built here would it take in your opinion?

    Chance you have a link to the heatsinks you used so I can figure a cost on this build?

    Sorry if some of this has been covered.

    Thanks!

    David~

    The function varies slightly, but it's still based on the inverse square law. It amounts to mathematically moving the source further away from the target to more accurately describe intensity losses.

    I really do need to get a fast, wide prime like that. I used to have a Sigma 8mm fisheye, that thing gave great night sky shots after a slight lens correction. Better believe I'll break out the DSLR once the QB's get here. I'll have things to share.

    i'll hold you to that :) 8mm wow thats wide! my fisheye is 15mm. The whole Sigma Art range is absolutely phenomenal. i used to shoot pretty much only on Canon L series but not any more! The sigma Art stuff is sharper and half the price. Their new 85mm just scored the highest score ever given to a lens...

    Yeah it yielded some awesome night sky shots up in the Cascades. I had the opportunity to use the 100-400 L IS II USM (with a 1.4x extender) in Tanzania. Phenomenal. I was paranoid about such an expensive rental, but it was worth it. Edit: and challenging, really.

    All I have on hand is an EF kit lens. Not the sharpest lens in the bag, ya know? Need a better :leaf: lens.

    if i see a lens i want to try/rent these days i buy it from amazon, use it for a week and then send it back telling em it was soft ;) free lenses for life yo! if i really like it i might buy it...

    Love a night shot - tanzania, that sounds epic! never shot at 400mm man, wouldnt mid one for the moon shots :) any lens is a good lens in my book man, you can work it!

    I feel that. Yeah, without the extender the effective focal length was 640mm, with the extender it became 896mm. Crazy. Needless to say I didn't use the extender much.

    I'm using all-white components on the plant-facing side of the quantum lights I'm building, save for some orange-yellow kapton tape and, of course, the yellow LM561C's. Here's hoping they look as good as I envision. I think I can get them down to about one inch in thickness. We'll see.

    Nope. Sorry. That is incorrect. Please do more research before stating claims as fact.

    Just google if the inverse square law applies to lasers....
