![]() So there seems to be never-ending debate between Cree and Bridgelux in DIY leds in reefcentral and nano-reef. I was thinking what you people think and if you are doing or have DIY leds, which LED emitter do you use?
Keeping Cree at 50-70% while running Bridgelux at 100% (with fan) seems to be of the same thing. But people still say running cree at lower rating expands its life. But I am not pleased with the justification since I am pretty sure a DIY running for 5 years and another for 10years doesn't make a difference; since you will obviously change it at some point well before 10 years. Opinions please ![]()

![]() Cree is owned by General Electric.... Toshiba just bought Bridgelux....and throw in Philips Rebels too. Cree is the more expensive ones with newer technology coming out every few months it seems ( see latest XM-L2) with a large capital to fund its R&D. Some people say the rebels ( see Stevesleds (on sale right now) , & nano-box-reef lights) are actually better in terms of the spectra though... I would go with a mix as some companies are doing it ( eg. Crees & Philips by http://www.marinedepot.com/Maxspect_...FILDTN-vi.html ). Nowadays on the DIY front, people are doing the full spectrum layouts as opposed to blue and white offerings though.
Also, Epistar, a taiwan based company, shares some of the same patents as Cree and is the cheapest of the 4. regs msjboy |

![]() I've run both and I prefer the Crees, IME SPS respond better under them, no idea why but they just do. Lower output also means higher efficiency as in you're using less power. Not too many LED fixtures out there using bridgelux either, from a manufacturing point of view I would conclude the Crees are the favorite by far. Crees are also pretty cheap now, not much point using budget LEDs these days unless you have a fairly large build. I also like the Luxeon's in terms of spectrum for the cool blues and royal blues.

![]() I guess you have to consider worth while in terms of what exactly? A 20 gallon tank won't require very many LEDs and you can use less crees for the same amount of light given by more bridgelux. I don't think you'll have much potential for any money savings. So why limit yourself to bridgelux?

![]() Pretty hard to buy a kit without drivers but Cree LEDs can be purchased for around $3.50 which would be $84 for 24 plus if you only need 70% or less to achieve the same output you only need 16 LEDs which would be around $56. Rapid LED also sells pretty nice anodized heat sinks that accept splash cards and hanging kits for around $30. Realistically you're talking about $20 max in savings.

I grew SPS very well (grew a cantaloupe sized birdsnest from a 1" frag in just under 8 months) in a 20 gallon tank for about two years... and I didn't even own a skimmer at the time! Just regulated my feeding and did weekly water changes. I recommend Rebels over the Bridgelux, and put Crees and Rebels at the same quality level. |
