Right now I'm running a custom RapidLED setup with 70 Cree LED's on my 120 (4'x2'x2'). I'm not pleased with the color and I think fixing it would require replacement of a lot of LED's, which is a fairly expensive overhaul. Even then, I can't get the lenses to stay on.

So I'm considering SB Reeflights. I like their spectrum and I think the size would fit my tank better. They are 16x8 vs 20x6 on my current lights. I could use more front to back coverage, and the shorter side to side would help to avoid light loss from the center brace.

Advantages:

Possible better coverage
Better spectrum
Less wiring mess (currently 8 wires to each heatsink, 16 total)
Lenses that don't fall off

Disadvantages:

Slower drivers. Could possibly mod one of the models with PWM drivers to get better response for lightning, etc.
Possible loss of intensity, although this may not be a problem since I'm not running lenses at the moment.
Will have to modify for dimming. "Apex Ready" model available soon is a possibility.

Any thoughts?

Apex ready model has be soon since last year. Troylong has a kit for cheap. Great spectrum, you'll be happy. The pwm drivers aren't responsive either. Actually the responsiveness may have been better with the analog.

Looks great!

That's disappointing about the PWM drivers. That eliminates one of their possible advantages. The Apex-ready models will be more expensive and I'm not sure the price difference would be worth it when I could mod some of the standards for cheap.

What exact lights are you using right now, Lee?

I'm using ebay block boxes that I've modded for control, better fans, pwm drivers and sb reeflights boards.

I went ahead and ordered two of the SB Basics. I'll just mod them for 0-10v dimming. If I really want lightning I can always put together a small fixture with a few LED's and an LDD driver. Not sure it's worth the effort, though.

Where did you get the PWM drivers, BTW?

I'll send you a PM with the info on the PWM drivers. They are good for the fact that they turn off completely and dim much lower than the analog.

Sounds good. Looking forward to the info. Did you have to use a PWM inverter circuit?

Nope but needed to use the included dimmers
