Lighting

Which aquarium lights offer good lighting for a low-tech planted tank while maintaining a low(er) power bill?

If the power bill is the biggest concern, then I'd definitely look into LED's. I don't have a lot of experience with them as far as planted tanks go, but their power consumption is hard to compete with.

If LED's aren't a viable option, the next route I'd go with on a smaller (<29g) tank is screw in CFLs.

Okay Thanks! I will look into the LED's. When I told my husband we needed at least 5000K he said "I don't think so! Our power bill is high enough!" We live in Alaska and our monthly power bill is on average $400. IOt's ridiculous! When we paid our latest bill, the company said qoute: We are at our peak rates :end qoute.

Just to clarify, 5000k is a kelvin rating. Kelvin is basically a rating of light color, not light intensity. That means that a 2500k bulb and a 10000k bulb are using the same amount of energy, they just have different colors.

This is a long read, but it breaks it all down.

Aquarium Lighting; Reef, Planted Light Information. PAR, Bulb, Watt, Kelvin, Nanometers, MH, LED.

I like using the bulbs around 6700k (daylight) range, full spectrum for my planted tanks.

Oh really? Gosh...see I read that read you linked me too and took notes even. But when I told my husband what I had learned he said "don't believe everything you read" and I never mentioned it again. I figured he knew what he was talking about since he has always handled the lighting in our house and is always reading up on stuff. Sounds like he might need to read a little more about lighting He's so stubborn though. I might not be able to get him to even hear me about the meaning of kelvin rating.

The yellowish tint is a lower kelvin rating on the bulb. Shoot for a daylight bulb (~6500k) for a brighter white, or 10000k for an operating room type white. Any higher than that and it'll start looking more and more blue.

Hope you figure out how to get it across to him, maybe he just has to 'stumble' on it himself. I know I can be stubborn sometimes myself, so a well timed and well placed article could work wonders.


I know what you mean about the power bill, ours is pretty high here also, for the opposite reason.

I get mine from home depot, but walmart does sell them as well. My local walmart fish section actually has replacement bulbs in the fish section if your hood bulb area is too narrow to fit in a spiral CFL.

This is the one I was thinking of.
