numbers look very promising. mostly on par with what is advertised on the documents.
I started to test par on all channel individually, but realised chan 1 & 4 only gives about 30-50 PAR each, directly under the lamp, while chan 2 (moonlight) gives less than 30 PAR. So, I did all 4 chan @ 100%.
Here is my setup. T5HO and middle R420r are off.
circulating pumps are off, but return pump is still running, giving minimal water agitation.
Lamp is 8 inch above water, 12 inch from front, back and side.
Thats my top/center reading.
(I put down the maximum number I was able to get at each spot)
Due the that ugly birdnest taking all the place on this side of the tank, I was only able to take front readings. But, they are almost exactly what is advertised.
I will install the second lamp this weekend and take some more readings.
But I must admit they look like very good lamps for the price. They do not offer wifi, but IMA, its a prety much useless feature for lighting for the number of time I change their settings...
