OK, I just received my light meter, and had to test this idea about HPS light penetrating farther then Compact Fluos..
Here are the results.
1 - 430 watt Son Agro. with tempered glass sheild, at 15 inches away = 5000 ft candles at 82 degrees at 23 inches ( added in the plant hight ) = 4500 ft candles at 80 degrees.
4 - 55 watt Biax high out put Compact Fluos. 2 - 6500k and 2 3000k with reflector. at 2 inches from light 4750 ft candles at 78 degrees. at 10 inches. 4250 at 70 degrees!
the lights were tested in the same location, above the same plants.
From what I can see there is Such a minimal difference in the two ( except the fluos are brighter, run cooler and have absolutely no ballast hum! ) This is before I have added the two 3000k side lights.
Please let me know what you think or if my analyses seems flawed
Also after having on the fluos for a few days now and have not noticed any slowdown or changes in the growth rate or look of the plants...
Please look up in this thread to see the complete fluos..
