I am looking for opinion/advice on LED lighting.

I am wondering if the 24 LED w/ dimmable drivers would work as a retro fit for the current Cadlight fixture I have. If so what kind of optics, heatsink, and how high above the tank would it need to be? Currently there are no fans in this light.

Some pics of the light in question:

24 inches long

The opening on the underside is about 6 3/4 inch

The 24 kit should work, you can probably use a couple of the 1.1" x 24" heatsinks but you'll probably want a little bit of cooling/airflow in there if you're going that route. With the lights that close to the water you might not need lenses, in which case you can go with the 24 LED actinic supplement kit and request two 24" heatsinks instead of one 48" heatsink and also you can get half rb/ half cw (or whatever color mix you want).

Thanks for the response. The light can be moved to any height. Would raising it and adding optics provide a better color spread, or increased intensity?

Would it be wise to figure out a way to put in a fan if I went with the LED retro? I was thinking of maybe drilling some holes in the middle top and putting a fan there blowing out.

No, I want to gut the light and just use it to house the LEDs.

The current 150 W bulb needs to be replaced, and one of the T5s is busted and keeps blowing bulbs. I figured rather than fixing it and replacing the three bulbs I would put that money towards an LED fixture. I like the look of the light and think it goes good with the rest of the tank so that is why I want to retro fit it.

I know almost nothing about LEDs. I assume those abbreviations are referring to the white LEDs. I have heard people don't like the cool whites, but I really have nothing to compare it to. Also I think the Rapid LED kits only come with the cool whites.

I really like the color of my 12k MH with the t5 actinic supplementation. This would be my first LED project so I need to keep it somewhat simple. What are your thoughts?

How would the output of this retro kit compare to my current 150W MH?
