I wanted to see what types of lights you guys use on your tanks. Right now I have LED's over my 38. What kinds of LED"s do you guys use.

Most of my LEd's are DIY now. I do have a 120EVO modified that I am running.

Ai sol blues over my 180 660 150 frag tank. Hydra 26 over my 40 rimless cube. Have been running ai sols for 5 years and love them good growth and color

Custom spectrum 2X 60W LED panels from China running at half power and my corals are already coloring up and growing faster than they did under 2X 250W 14,000K MH. 2X 10W red/blue LEDs over the algae scrubber in the sump.

I have 2X 165W full spectrum LED's that I am running on my 75G tank. What power should they Blue and the whites be at? I am not sure if I have enough to reach everything in the bottom of the tank.

Sounds like it should be plenty.

I've read that the whites should be at 50% or lower . But don't take my word for it .

I want enough to grow the coral but not kill or bleach anything.

It's aboot playing g around with it till not only do you get a color you like but find the adjustments that your corals best respond to. I've always had more luck with my lights more white then blue. Not to mention I think the deep blue that LEDs produce is ugly. I like a more natural look. Corals still pop and look awesome but it's not all flooded out with the blues

330W of blue and white LEDs over a 75G? You're definitely getting plenty of light at the bottom. I'll bet that at 100% you'll fry just about everything. The blue light is very high energy, even though it doesn't look all that bright to the eye. If the whites are cool white, they may also have a high blue output. I have a new 120W multi-wavelength LED (heavy in the violet-blue region, and supplemented with a few whites) running at an average of 50% power over a 110G and the corals (including chalice, acros, montis, seriatopora) are really coloring up and growing fairly fast. I'm not sure whether I'll be ramping up the intensity any time soon.

What were you using over the tank prior to the LEDs? Based on my experience rapidly bleaching corals when switching from 1200W of MH and VHO to just 230W of white and blue LEDs, I suggest you start with both sets of LEDs at well under 50% at first, gradually increasing the power over several weeks to the level at which you start noticing increased coloration and growth. You'll know you've gone too far or too fast if you notice polyps closing up at a certain intensity. That would be a sign that you may have gone beyond photosaturation to photoinhibition. You may find that a single 165 is more than enough, even at less than 100%.
