On eBay, just now, I read through a listing titled:
"50*3W 90W UFO Hydro LED Grow Light Quad-band 71:1 for Flowering"
It explains that it uses 3W LEDs, at an actual power of 90 Watts,
with the detail: "Bridgelux RED 35 Blue 5 Orange 5 White 5 LED".
I've believed that Bridgelux sold pretty good stuff, so when the
text _explicitly_ listed the light's specs as 2700 lumens, I was
disillusioned. That's only 30 lumens per actual watt !!
My 400W HPS generates 55,000 (!) lumens of admittedly yellow light,
but even granting a 4X advantage for an ideal PAR spectrum (which
I highly doubt) that'd put this light at an actual 1/5 of my HPS.
Where are the beyond-100 lumens-per-watt stats of red and blue
light that everyone alludes to ?
I _do_ also run an old Taiwanese 300W LED light, so I'm asking as
a potential customer for some new lights, too, inspired by recent
hype saying "hey, they're really already better than HPS".
Let's have actual _numbers_ for LED lumens -- something that
can be tested and verified. Let it be one number for each band
if necessary. We can handle the truth. Stop filtering out the
complexity assuming our brains are too puny to handle it.
Maybe this level of universal obfuscation is now just par for the
course, when manufacturers, themselves, _all_ start giving their
newly produced chips -- the ones that draw 2 watts and produce
just twice the lumens of their previous 1 watt chips -- the
title "3 watts". But _I_ don't think of this as a "good thing".
Is it just me? Or do Buffalo Wings taste like chicken?
