two of these work?

How many K?

 

[sfin52]

Coralife bulbs are 1000k I'm getting two of them that's 20000k than adding a couple of grow light bulbs I believe most are at 7,500 so that would be 35k. That's for a 55g

 

[Katrina71]

Do you want 32W or 25W?

I googled. Those should work. Coralife is 32w.

It should work.

I don't know if you're messing around or not sfin52, but that is not how Kelvin works haha.

You would have 2x 10k (daylight) 7.5k is yellow. So you would have ayellow white light color. Kelvin measures the temperature (color) of the light.

My preferred Kelvin is 14k. A nice bright blue.

He's using it for macro

Why? I may have misunderstood

If you have a 10k bulb, and add another 10k bulb you end up with light that is 10k. If you add a 7.5k bulb to it, you end up with light that is something less than 10k.

56,000 kelvin is daylight.
10-14k would be nice though.

8k.

I see what you're saying. I missed that. I was just thinking blue for coral.

 

[Brew12]

8k.

I'll trust you on that! We have reached the extent of my knowledge on K.

Coralife labels them as daylight 10,000k
