Interesting. I have serious doubts because the multichip LEDs are still 1W chips underneath those lenses and therefore they are weak penetration. Multichip LEDs are just .6 or 1w chips, repackaged in a way that will find another unwitting sucker. I'm sure you've read plenty of people...

Slightly off-subject... here is what I've been growing in a 40gal aquarium with the XT-E: 6x Q4 WW and 12x R50 CW @ <1050mA

Cool I looked at MrFlux's thread. However I lost interest because I got annoyed with the langauge and insults by page 3. Hey we need to talk about these WW LEDs more. I've been using the binned XT-E I mentioned on aquarium aquatic plants, in combination with CW. Aquarium plants have slightly...

Also it looks like the binned XT-E WW and RB (D6 & D7 bins) are cheaper on reefLEDlights.com... that's also where I'm planning on ordering the Meanwell LPC 35-700s

I was considering the Osrams but I really like the convenience of using 20mm stars with BJB soldierless connectors on T-slot heatsinks. No one likes to deal with 400 soldering points haha. Also I'm planning on using Arctic Alumina thermal paste because I doubt that there is much difference when...

I'm planning on using the Meanwell LPC 35-700. Each can run up to 13 LEDs with a forward voltage of 3.4. I know that it will end up being a lot of drivers, but the 35-700 is the most reliable, longest-lasting driver ever manufactured. If I were to do anything dimmable, though, I would use the...

After reading Supra's thread, I'm eagerly planning a 182 to 196 LED light to be run @ 700mA Due to efficiency of ballasts and diodes, this light should perform at <525W while an equivalent HPS light will use 1250W Plant needs: Chloraphyll A 680nm, 445-450nm Chloraphyll B 470-480nm, 650nm...

Hey I signed up for this forum just to pick your brain. I've read your DIY LED 220w thread- twice... before signing up. I own a small aquarium store and I'm using my knowledge of LEDs in aquaculture to design a 1000W HPS equivalent light... that will exceed Black Dog. I think we have the data...
