I'm getting rid of mine as soon as i figure out which one of the SB lights I am replacing it with.
Actually I do know. With the whites and blues ramped to 100% they were ok 1700 I believe on the par meter. I've got the marine orbit pro.Is there any chance one of you would get a lux meter and measure the output from this light at your water surface? I'm curious to know!
Just for the record there is a pro version of the orbit which is more intended for stony corals. I'm not sure it's a fair characterization to say that the non-pro would be unable to grow stone equals though.

I wondered that with the meter for a second myself, we then switched to a 4 bulb t5 and had great readings from the bottom up.2000 par is equal to direct sun at sea level.
Most stony corals are going to be completely happy even if you were giving them 800-1000 par.
There has to be something wrong with your reading or your meter if there was no reading at the bottom of the tank.
Attenuation from the few inches of water that's in any of our tanks could not cause that level of drop.
I'm curious what reading the folks who have the non-pro model would get at the water surface .
Awesome share! But doesn't lux measure only what light can be seen and not the intensity? Or am I crossed here (wouldn't be a 1st).I am very new to lighting parameters, etc. I have a lux meter on my phone. This was not measuring through my glass lid as there is not enough clearance to keep my phone dry. I placed the lights over my phone and took a screenshot.

The Orbit running about 60% blues and whites (I am not positive I am reading that right, as it shows 60% and then jumps to 100 when I press max intensity. I am still learning programming on this thing.)

If they're happy leave em beAccording to Wikipedia, 1 lux= 1 lumen/m^2.
I wonder if these two lights have a summative effect. With the two, do I have over 10k at the surface?
I also don't know how glass affects it, or what will happen when I ramp up these lights to full intensity. I don't want to scorch my corals or mess up my programming to find out.

well yes. BUT we see light. so it is measuring the intensity of the light we see. it is actually the amount of light present. therefor the intensity of a light that can be seen.Awesome share!

Yes. I am taking your advice and increasing the photoperiod first, then bumping up 5%/week.I belive we have spoken and I assured you you likely have plenty of room to increase the intensity. SLOWLY.(and watch the corals) That was based on the knowledge of the 2 fixtures mentioned, depth of your tank and your settings.
