I can't wait for them to come out with 10w leds.
On what are you basing this?<a href=showthread.php?s=&postid=13974274#post13974274 target=_blank>Originally posted</a> by beetlenut33
Those LEDs will not work long term. They are low power and don't produce any decent light output. Forward current is about 20mA.

On what are you basing this?
According to the Lux meter measurements, 7 of these tubes are comparable to a 400W HQI metal halide. Unless the methods used to benchmark these different lights are terribly flawed, we can assume the usable light output is at least as good as your typical MH 250 watters. We know with certainty, success with SPS can be had with only 250 W MH, therefore, I don't see any reason why these would not work.
LEDs are improving fast, not only in the wattage it can use, but also how efficiently it can use that power. LEDs can also be used to beef up specific target wavelengths since they can have very narrow peaks, also increasing efficiency. I currently run a set of DIY LEDs for actinic supplementation. The array has a total of 72 LEDs (20mA) each. It is plenty bright and wavelength peaks at 420 nm and 470 nm (two types of LEDs). If I had known these tubes existed, I prob would have saved myself some trouble...
For those of us who are "shimmer" junkies, LEDs and MH are the only way to go.

Saltwater creep,
Cancel the order on your PAR meter, I am releasing the readings.
I cannot stand these Engineers, contractors, students, know-it-all-ers keep educating the public with wrong infos.
so here it is.
LED is here and MH will become histroy very soon.
Tim

how did he get himself booted?
