Yup. Meq/L
I've got pictures of what used to happen to this same reef when I would dip below 2.0 new/L back when I had bright metal halide lighting. (>60,000 lux)
These days the reef is carrying slightly more nutrients and the lights are significantly less — around 40,000-50,000 lux. There doesn't seem to be nearly as much sensitivity.

A Coralife Aqualight. No side-channels because I though those were a waste from Day 0. 
It's too bad these weren't more popular as it's been a great fixture. Worst complaint is that the cover glasses were a bit tough to slide out for bulb replacements.
This fixture has been decomissioned for a few (several?) years and I'm just now getting around to measuring it. These bulbs are at the 6 month mark where I would have started to see an impact on corals and where I would have changed the bulbs.
As it says on the chart, these measurements were taken in air. Note the even lighting at the bottom of the "tank". I really loved this fixture and these bulbs.
That's a 36" fixture on a 36" tank.
I ran it on my 38 Gallon first, then later my 50 Breeder.
Hoping to post a spectrum photo of each bulb later on as well.

Just going by the numbers, my 27" Razor (the 50 Breeder's current light) is at least somewhat comparable in power at 100%.
Again by the numbers, my DIY fixture (38 Gallon's current light) is more comparable to the middle section between bulbs! (Actually about 15,000 lux.)
I still need to measure the DIY fixture (and Razor) like this....so far I've only got surface measurements for the GU10's.

Thanks!
That a nice hystrix in the top of the photo too, right?
I wish I were fluent in every fixture's color settings and power capabilities, but I'm not quite there yet. Do you have any idea what your system peaks at mid-day in terms of lux or PAR at the water level, for example?
(If you don't have a light meter at all – say it isn't so!!! – then by all means necessary you should at least acquire a lux meter from ebay or amazon. The cost (here anyway) is about $10-$15 including delivery. You can search for the model I use, for example, the simple "LX-1010B".)

Just going by a published, unofficial converstion factor for Radiums (51), that puts PAR on my sandbed at about 78. I always had great luck growing stony corals in any zone. It was always mostly-Monti's.
I will admit that once corals got up into the 20,000+ lux zones they had an unreal amount of irridescence.
Wow, I had expected a LOT higher numbers for a 150w. My coralife hit 40k at 12in or more(i forget now).A Coralife Aqualight. No side-channels because I though those were a waste from Day 0.

reflector maybe?

As I noted, these are used-up bulbs (note they wore unevenly....wish I'd been tracking this over time) on a reflector with wi-i-ide spread. To wit....
12,000 lux way up in the middle...and then notice where the (wide) beams cross to give a nice boost mid-tank t0 keep over-all coverage smooth and even.
It's a brilliant fixture and it performed awesomely. I really wish I could afford to fire it up again.
This is also the lighting effect that the Kessil's seem to emulate better than any other. (Wish I could see some in person.)

yes fairly new is looking at the bulb. I got a 14k phoenix with it that was in rough shape but got similar readings.
my other MH fixture got crazy readings, the hot spot was 60,000 and the fall off was almost nothing. I got both fixtures n bulbs for $40.

@saltyfilmfolks Also take note of your power usage from the wall. Curious if your 150's are being driven at the same wattage as mine. (You'd think so given the same brand, but who knows.) The 340 watts/90 power factor I got was from both lights running simultaneously.
yea I mah have a better ballast, it weighs a TON and is like a brick.
