* Faint "dayactinic" looking bulb, simulates deeper water. If you light this up over your tank in complete darkness, it will look more blue than white in color.
* Nice 'faint white/blue light' if you are trying to keep any deepwater / lowlight animals like eels or octopus, this is an excellent bulb!
* We must emphasize that this bulb looks faint compared to a 10,000K, Blue 7,100K or Actinic 03 bulb. Stand alone, they are a nice light.
* There seems to be a hint of actinic type fluorescing, but nothing major.
* Works in any standard Straight Pin socket. * 36W Compact Fluorescent style bulb.
* Approx Length: Glass Tube= 15 1/2", Overall (end to end)= 16 1/2"
* Approx Width: Glass Tube= 1 1/2"
