SDS, there's another EYE opener article in the current LEDMagazine discussing drift.
They show side-by-side pics of a 5300 lumen led after only 4000 hours v the same led but new. Pretty shocking- not in a good way
Makes the e-shine 5G look better and better, at least if we can get drop in replacement chips- and hopefully cobs http://www.eshinesun.com/growsun.html

O-M-G It's Here
Surfin the net for where to buy cobs I came across this DIY thread
IMO no need for the regular bulbs as overheads, drop or sde lighting maybe, but
Feast your eyes on this...

Not sure what you are referring to
If it's "no need for regular bulbs" look at his light, he incorporates 2 x A27 sockets horizontally

I guess you are being sarcastic here....

nice thread off course,i'm study a spectrum again,in a lamp with 2 chan, one for veg and the other for flow,
to experiment, I do not know if at the experimental level is more interesting to have 2 channels are completely separate and mix:
example: first prevalence CW/NW channel, the second channel predominantly WW/R/DR;
or is it more interesting to create a channel with spectrum suitable for vegetative and other channel with spectrum suitable for flowering.
In both cases, I ask you in the case of vegetative, what percentage of blue and red should be according to your criteria.

Been in contact with BML
Wait till you see what they're up to
They have a program that allows you to select your own leds and get real time info in the right tower
Here's the blend I selected
Thoughts?

in honor of @stardustsailor , the eightballer is ALIVE
bridgelux CW and WW, and some chinese 640nm reds. This panel is considerably brighter than my old MerryWu panels (driven with the same driver) as measured by my cheap lux meter.

@BinGrower , I believe these type panels (higher quality asian 3W leds under-driven @300-350ma (1W)), would be ideal for the smaller bucket grows (5GAL) instead of the cheap "180w" UFOs. They could be placed on top and sides. This is about $14 worth of parts plus the driver (which can be as cheap as $3) for 24W of fairly efficient light. My guess is ~30=35% but I haven't been able to confirm yet.

Wouldn't that arrangement be very lacking in blending of spectrums?
What's with the reference of 24" of water? Am I missing something? No wonder why I can't turn out some real fire, I'm not growing under water lol

Definitely. I think most opt for the UFO for the simplicity but if that's not your thing then what you're describing sounds great. What kind of light levels would you expect from those 24W?
