Response from Tropical Marine Center to my multi manufacturer email:

Following your email of yesterday, I’ve taken some readings from two of the units we recommend for planted aquaria. These were taken using an Apogee Model QMSS meter. The lights are mounted 7” above the water surface (this is the height where we achieve the best balance between shimmer effect, light spread and sufficient PAR, given maximum water depth of 20”. For deeper displays or where higher PAR is required at substrate, the lights would be mounted closer to the water surface).

The readings I got were as follows:

AquaBeam 1500XG Ocean White (10 x 9000K Cree XP-G diodes):

231 PAR @ surface (7” through air)
161 PAR @ 3”
104 PAR @ 7”
78 PAR @ 12”
52 PAR @ 18”

GroBeam 1000 Natural Daylight (10 x 6500K Cree XP-E Compact PowerLEDS)

195 PAR @ surface (7” through air)
120 PAR @ 3”
80 PAR @ 7”
52 PAR @ 12”
41 PAR @ 18”

I’ve attached the relevant pages from our aquatics catalogue – if there is in further information you require, please let me know.

Kind regards
