Paleoreef103 Posted May 25, 2013 Share Posted May 25, 2013 Now if we could fit a big optic/reflector onto this beast, it'd be perfect. Link to comment

Tamberav Posted May 26, 2013 Share Posted May 26, 2013 This thread makes me want to DIY an LED build.. I'm scared. Link to comment
Tamberav Posted May 27, 2013 Share Posted May 27, 2013 1:1 neutral to RB spectrum too. Anyway, what does this chip look like over a tank!?! ^^^ Thisss!!!! WTB pics! Link to comment
GHill762 Posted May 28, 2013 Share Posted May 28, 2013 Interesting.. going to have to remember to keep an eye on this. Link to comment

sageblade24 Posted May 28, 2013 Share Posted May 28, 2013 Love the Lumia 5.1. I would love it even more if we could see it over a tank! Link to comment

jedimasterben Posted May 29, 2013 Share Posted May 29, 2013 So we all need to pressure Milad into making a multichip hyper violet. Like the ones AC-RC sells, but those put out, at most, around 4200mW of violet light... if the same style were made using the 430nm hyper violet, the same nine diodes would push at least 6500mW and have normal (700mA) amperage requirements (teh AC-RC chips are three strings of three in parallel, so it needs 11v 2100ma). Methinks it should happen, what say all of you? Maybe if they could squeeze in twelve diodes into the package... that's 8600+..... I need new pants, guys. Link to comment

Milad should use the base of the Lumina 5.1 with a channel of Cyan, another of Cool blue, one True Violet, and two hyper violet channels. so 10 Cyan, 10 CB, 10 TV, and 20 HV. put that in the center and circle it with 2 Bridgelux 950B or 1350B and six royal blue Luxeon M... I blinded my mind's eye trying to imagine that. Link to comment
Adam_T Posted May 29, 2013 Share Posted May 29, 2013 Here is my full spectrum lit tank...it is a Nano Box Reef LED build called the "Mini Tide". It is for nano tanks 14x14 and under. I have it over a Innovative Marine Nuvo 8g at the moment... -Warm White / Neutral White / Cool White and Violet on one channel... -Cyan / Blue / Royal blue on a second channel -Mix of 60/80 degree optics -Total of 13 LED's. -Both channels are independently dimmable. My corals love it, and so do my eyes. Love having a full spectrum LED setup. I have had AI Nano in the past, and a few DIY I built....but ended up switching back to T5HO due to me hating the crisp icy blue look of royal blue with cool white build. Well....set up a nano tank and I can't have T5's so I went with this. LOVE it. This is what the unit looks like above a tank....(mine is black): Link to comment

I agree, would be pretty sweet if he made one with 3 true violet and 6 hyper violet! Link to comment
jedimasterben Posted May 30, 2013 Share Posted May 30, 2013 I agree, would be pretty sweet if he made one with 3 true violet and 6 hyper violet! Nah - all hyper IMHO. The output of the 430nm is much higher, and the fluorescent effects are much higher, as well. Link to comment
blasterman Posted May 30, 2013 Share Posted May 30, 2013 Warm White / Neutral White / Cool White Why in the world? What this results in is something like neutral white with elevated green. Link to comment
topjimmy Posted May 30, 2013 Share Posted May 30, 2013 I can't believe how fast LED's are evolving. It has only been a year at best since I built my FS array using Steve's Leds. I almost can't wait for what is to come. I think those multichip leds are the death knell of t5 and mh. Link to comment
Adam_T Posted May 30, 2013 Share Posted May 30, 2013 Why in the world? What this results in is something like neutral white with elevated green. Results in sweet coloring. Dave at Nano Box Reef, and myself have tested numerous types of LED's, from manufacturing companies, to color combos, par levels, spectrums of multiple combos....etc...etc....etc. Color looks awesome, the spectrum is amazing when blended with the other LED's listed, and the colors look awesome and are very healthy.

Paleoreef103 Posted May 30, 2013 Share Posted May 30, 2013 Nah - all hyper IMHO. The output of the 430nm is much higher, and the fluorescent effects are much higher, as well. Honestly, no reason not to hit the 410nm cholophyll a peak with some 405nm peak or 420nm peak TVs. Yes they're less efficient, but cool blues are less efficient than royal blues and the difference between a 430 HV and a 405 TV is similar to the difference between royals (~450nm) and Cool Blues (~470-480nm) and you still advocate for using cool blues and royals. Yes, I know our eyes respond to the cool vs royal blues more decisively than we see between HV and TV, but I don't see the point in neglecting the TV range. Different strokes for different folks I guess. Why in the world? What this results in is something like neutral white with elevated green. The cools when combined with neutrals and warms make the light brighter/crisper and can help balance out the purplely tint you can get from using exclusively warm and neutral whites. There are obviously many ways to do this, but that's Dave's way and I respect it. I'd never use a light where cool whites were my exclusive source of white light, but they can have uses.

Horerczy Posted May 30, 2013 Share Posted May 30, 2013 For me cool whites make good moon lights. Link to comment
jedimasterben Posted May 30, 2013 Share Posted May 30, 2013 Honestly, no reason not to hit the 410nm cholophyll a peak with some 405nm peak or 420nm peak TVs. Take a look at the absorption graphs of chlorophylls a and c. These two photosystems can only take in so much light. While the 430nm chips have their peak at around 428nm (precisely at the peak of chlorophyll a), they do touch on the 410-ish-nm shoulder of chlorophyll a. But again, the photosystem is limited in how much it can absorb, and because of such, I would recommend sticking to the higher-nm chips. Yes they're less efficient, but cool blues are less efficient than royal blues and the difference between a 430 HV and a 405 TV is similar to the difference between royals (~450nm) and Cool Blues (~470-480nm) and you still advocate for using cool blues and royals. Yes, I know our eyes respond to the cool vs royal blues more decisively than we see between HV and TV, but I don't see the point in neglecting the TV range. Different strokes for different folks I guess. Royal blue and blue LEDs do two very different - one is photosynthetically significant, one is aesthetically significant. Efficiency doesn't have anything to do with it - blue LEDs put out more light than royal blue LEDs do, at least to us, it takes several royal blue LEDs to appear as 'bright' as a single blue LED. Comparing that to the low-violet range is apples and oranges. Link to comment
fishnlou Posted May 31, 2013 Share Posted May 31, 2013 Nah - all hyper IMHO. The output of the 430nm is much higher, and the fluorescent effects are much higher, as well. I thought i read in one of your older posts that 410nm is more important for keeping clams. Do you still feel this is true? Either way, if Milad made a 9 diode hyper violet that would still be pretty amazing. Link to comment
