Bridgelux is about 15% to 20% less efficient compare to CREE, but CREE is about 30% to 40% more expesnive.
This only set true when the bridgelux and CREE are on even setting.
2)watts per LED
With lack of information on rapidled site, it concerns me a bit.
It says total 28 LEDs, which means some LEDs are at 5w but running with lower current to adds up to the 90W,just like the one I am selling,
The only thing different is that all the LED
made up the Pharos LED
are all CREEs and for Onyx, 1 of the LED
is made by OSRM (Germany) and 4 of the LEDs (violet ) could be made by either bridgelux or EPISTAR.
The reason why I said they rushed it is because most these fixtures are not able to control by the brand name controllers and most unlikely can be upgraded in the future. That is the main reason why I said they rushed it and the price for a no function and none upgradable fixture price at $279 is a bit too high. If I am going to save money upfront, I would of go with bridgelux chip which cost about $200 for 120W fixture with dimming. And for those people that doesn't concern about up-front cost and want more functions, they would of getting some fixtures that already able to do dimming with timer and effects for maybe extra $200.
