yes it is, but it tells us nothing of the quality of the light. there is only a specific band of light that is usable for photosynthis and that is what is important to us.
Snappy, we had a guy on here that was going to send me a luxton star and driver "on loan" for me to run PAR tests as he was claiming how good they were and that he was going to start producing a LED lighting system.. well in short I sent my address he said they were on the way.. 8 months laiter still nothing.
I do have a PAR sensor and have tested normal LED's very disapointing PAR output. less than 1/20th of a NO actinic bulb, so going by that if a luxton is 10X more powerfull we should still only see 1/2 of the output of a NO tube, but it would take about 5 luxtons to cover the same area.. and at 20.00 a pop it wouldn't be a cheaper method of lighting..
so if anyone has a luxton and driver they could spare for a week or two I will do tests and get some comparitive figures instead of speculation.
