Reef lights: what does 50/50 mean?
I am thinking of getting a power compact light, either a Blue Life USA SPS Power compact 65W 50/50 light bulb, or a 50/50 Power Compact Lamp 65W.
What does the 50/50 mean, is it like you can have the daytime light and a nighttime light? That is probably a really stupid question, but I am asking it anyways. Which would you recommend for a 10 gallon FOWLR tank with maybe a few mushroom corals or zoanthids. I am still in 'research' mode at this point by the way, (obviously)
Thanks so much for the help!!!!
If you look at the power compacts, there are 2 tubes that are connected. A 50/50 is 1 that combines the blue actinic and a white 10,000K into 1 bulb.
These only come on together, you can't have 1 come on at 1 time and the other at a different time.
If your fixture has room for 2 separate tubes, you can put a 50/50 with a 10,000K and have them come on separately. Some people think an actinic makes the tank look too blue, so that's a way of cutting back on the blue tint. But if you like the blue, and want to have the blue on by itself either before or after the white light is on [or both] you can use a 10,000K and an actinic and not use a 50/50 at all.
Another reason to use a 50/50 over an actinic is if you're keeping corals that live closer to the surface. The actinic is what the water would look like at a point deeper underwater.
