PAR numbers (PPFD) at various depths with K7 Pro II at maximum light intensity. Configuration of lamp support and aquarium overflow allows LED array to be a minimum of 6.5" from water surface. Horizontal adjustments to the lamp support allow the LED array to be centered over aquaria up to 24" wide, however, I did not realize this and the lamp was 5" off center. Depths were 17" deep (total of 23.5" to light), 13" (total of 19.5") and 8" (total of 14.5".) PAR measurements (every ~3.5") were made with an Apogee MQ-510 quantum meter with 'improved' sensor. Light was centered on the right side of a 120-gallon tank filled with water to the overflow level. PAR less than 100 micromole/m2/sec are colored black.
Quick question. Do you have analysis of any other fixtures, shown in this format? For comparison purposes.
