looks expensive for the output ......................................

Thou,
I'm not a expert but I have slept at Holiday Inn Express

 

[BOBBY_G]

$30 for $40W isnt ridiculous

compare it to the commercial RB panels

Hmm I have to place an order soon. Might be worth picking one up to play with. Grow some mean lettuce if nothing else.

ETA: Zero in stock

Hi BOBBG_G
thanks for showing this blurple cob.
Do you know how efficent this cob is in compare to deep red and royal blue monos?
If i remeber correct osram oslon ssl 150 deep red can be 50% efficent at 350ma and royal blue 52%efficent at 350ma.
i know that a 40watt mono cluster(at 50% efficent) would cost much more then this blurple cob, but i would like to know how efficent that blurple cob is

 

[BOBBY_G]

i know nothing about it. perhaps @welight can chime in

SPD looks white, listed as 2000K, photo of the chip covered in phosphors, but it's red/blue... Confusing.

 

[welight]

The chip does have a white phosphor layer so appears, white when powered(removes the harsh burple look) however it is just red and blue leds, you can see the MCREES test on these, the peaks are red and blue
Cheers

can you give us a stab at efficiency in umol/J or mw/W or lum/W?

can you give us a stab at efficiency in umol/J or mw/W or lum/W?

Let me check data on this, we did a spectral test, so will dig it out
cheers
