In original set-up I wanted to use npf-120 for middle power, but is not yet available,Meanwell had declared for December 2014... for this reason I'm looking for alternatives...

yes, i have read your work...nice work...now I know that to run hard,realy hard, is better the Vero29.... but I can not change,not this time, I've all heatsinks worked for CXA3070...

My idea, to stay on spec cree-tools, for example to pot near max 2.8/2.9A, the ventilation and heatsink can run without problem near 150w with low temp... but I have no idea if is possible and I do not know what happen if go over 3.0A and what is' the limit...

what can I aspect, to use a MEANWELL HLG-150H-42B for a single CXA3070AB ? it run 42v, 3.6A,on cree tools the limit for CXA3070AB is 2.8A - 41.64Vf - 116.587w... how will / will adapt to these conditions the CXA? counting on an excellent dissipation, maximum power that can reach?anyone have test...

beautiful work SDS... the COB placement it's perfect, not only for dissipation, but the "particular" position and distance between the light cones, allows exceptional values in lux and par flux, projected and concentrated, in a defined area... I think you have already see with instruments...;-)...

The cost of an high quality LED unit, is definitely higher than "commercial" products you know(most come from the same place)and it is obvious, but it is also much more performant, ensuring real powers, best spectrum, and can be guaranteed to last for many years without any problems, with only...

Newark: BRIDGELUX BXRC-27G10K0-L-22 BRIDGELUX BXRC-30G10K0-L-22 Availability: 0 Per the manufacturer, more stock expected week of 3/9/15... Minimum order quantity: 50 Order multiple quantity: 10 ideal to test would find 10 at a time not more ...

Thanks for your interest

exactly what you say. Also an infrared thermometer is perfect in this case.

I'm waiting to test the system to be included on the COB lamp , the ideal would be to insert the correct sensor near the temperature when the fan turns off, to understand you have to test and verify the real-time response of the sensor and the correct adjustment of voltage.The correct thing...

may be useful, in the case of a cooling problem maybe on single COB. The "setting" of the temperature depend on the sensor installed.

the lamp will be available in February...

congratulations SDS for a new lamp, the specifications are excellent ... now I'm going to read the fan spec, what you will use as a heatsink?

the idea is good but unfortunately the efficiency, to date, is very low and inconvenient as a practical application.... to dissipate 100 watts in a given area, would have to calculate how much heat you have to remove to get to the desired temperature... you can explore the cpu overclocking world...

thank you SDS and SupraSPL...nice work your...and nice thread realy...i'm working at the "monster" night and day.... I need help in many "aspect" .... professionally speaking ... you could create great things ... "potential"...i think is the right word to describe this...

what do you think to use Wago for the management of cable dimm of the three drivers and one Pot? any problem of resistence? alternative?

thanks guys are as always exceptional and professional ... the three drivers have to drive 9xCXA3070 .... 3x CXA3070 for one driver I copy you SDS and correct me if I'm wrong: for dimm at full power468W - from 10 to 100%: 1) 468/3=156 2) 156/185 *100 = ~84% 3) For one driver you will need a...

one question... I want to dimm simultaneously 3xHLG-185H-C1400B with one external pot.I need to set the lamp at 400w fix. for one driver i can use 100Khom, for 3 driver and one pot, applying the rule, I need 33Khom. the problem that models 33khom are not easy to find . I wondered how could you...

only 100 poor watts of 4xCREE CXA3070 in 70 days for one plant...in a closet with no ventilation or other sophisticated systems...the only fan is in the lamp... TAmb 25°C fix with lamp on...no junk part. total dried: 134gr....... no need of tons of watts for big result....the quality of light...

interesting curves are the 3000K and the 2700K-90CRI
