For some of you who like to tinker or just learn alittle here and there about new products here is some readings I took today with some different reflectors and bulbs.
These readings are using multiple variables including type of ballast, type of reflector and type of bulb.
First set of readings is from a 250 watt Hamilton Ballast with a Hamilton 14K bulb, and a Parabolic Reflector.(Bulb is 9 months old)
6" Below bulb (Above Water) - 600 par
1" Below water line - 120 par
6" below water line - 100 par
12" below water line - 90 par
18" below water line - 75 par
24" below water line - 40 par
----------------------------------------------------------------
Icecap 250 watt Electronic ballast, Lumenmax Reflector, and 9 month old Hamilton 14K bulb. Was also run with same hamilton ballast as above test, No noticable difference in par.
6" below bulb (above water) - 1600 par
1" below water line - 700 par
6" below water line - 620 par
12" below water line - 500 par
18" below water line - 375 par
24" below water line - 330 par
-------------------------------------------------------------------
Icecap 250 watt electronic ballast, lumenmax reflector, and new radium 20K bulb.
6" below bulb (above water) - alittle over 2000par (Meter shuts down over 2000)
1" below water line - 850 par
6" below water line - 660 par
12" below water line - 510 par
18" below water line - 400 par
24" below water line - 350 par
