Hello, Bodie, In reference to your inquiry, "Is this light appropriate for a fish tank?" As long as the fittings are compatible with the light assembly, you should have no problems with it. As with all light fixtures, make sure the light assembly is securely mounted to the tank and avoids moisture. Good luck with your endeavor and if we can be of help in the future you can contact us at The Home Depot.

Answer

Hey Jack - Thanks for the question. Looking up that GE product and it requires an F15T8 fluorescent tube. We offer three options for this lamp type: a Bright White (3000K), a Cool white (4100k) and a Daylight Deluxe (6500K). If you are looking for coolest/bluest light I would definitely recommend the daylight deluxe option. This can be found at www.homedepot.com/p/308390815

The Philips 15-Watt 18 in. Linear T8 Fluorescent Tube Light Bulb Cool White (4100K) works great it gives me a lot of good light over my commputer at night when I'm up and can't sleep.

What can I use to replace a F15T8/KB

Asked by Anita March 23, 2020
1
Answer

This bulb is the proper replacement. This is an F15T8 bulb that is a soft white or 3000K color temp. KB refers to "kitchen and bath" which generally have a soft white color temperature as well.

Will these work with 12 Volts ?

Asked by Anthony December 27, 2019
1
Answer

These lamps require a ballast to operate the lamps. If the ballast supports an input voltage of 12v and is designed to operate these types of lamps there should not be an issue.

Anyone know a replacement ballast model # used by 18" long T8 fluorescent bulbs?

IS THIS A GOOD REPLACEMENT FOR A F15T8-KB I DO NOT KNOW WHAT THE KB STANDS FOR

Asked by MISSY November 1, 2019
2
Answers

KB stands for Kitchen/Bath. It is less bright than the Cool White (CW), has a lower color temperature and lumen count (I cheated - I looked it up). I just replaced an F15T8-KB with an F15T8-CW for a light over the kitchen sink and am happy with it. It is somewhat brighter, but might be a bit glaring for some, especially if you prefer or need a lower light intensity.

False advertisement
Beware these are not 1,175 lumens. I bought them thinking they were the brightest I could find with the description stating the lumen output is 1,175 lumens but when they arrived they were the regular 870 lumen bulbs that the store has in stock. I could’ve picked these up a week ago in the store instead of waiting a week for something that is not the product it says it is.

3 stars and still using it?
I have been using this bulbs because the builder installed it when we got the new house few years ago and because didn’t want to change the illumination color of our kitchen. But this bulbs just last for 1 yr or so. Don’t know if this is normal because we use it every day. I just want to add photos of the package they came in to give also feedback on the delivery and manage of it.

The updated thinner diameter of the new lamp compared to the old style which is as thick as bigger wattage made me take a second look thinking I got the wrong one. I got the right one. Yey. Home Depot staff: please take note. You should know better.
