Approx. 325 lumens, 5 1/2" long.
Bulb with ballast in the screw-base, all one piece, makes an easy 12 volt compact fluorescent. These just screw into a standard full size light bulb socket of a table lamp, ceiling fixture, or other standard fixture connected to 12 volt DC. Just screw this in to replace 12 volt quartz or 12 volt energy gobbling regular screw-base bulbs. You can use the original switch on the lamp, or connect through a wall switch. (Socket must be wired correctly with + to tip.)
The compact fluorescent bulbs give four times the brightness of a regular bulb of the same wattage. Proven good reliability. At 12V, 7 watt uses about l/2 amp.
Choice of color is available. Choose either warm yellow (2700K) or cool white (4100K). Brightness of each equals incandescent bulb of four times the wattage.
Installation and use note: Polarity must be observed with the center tip being (+). And once on, the bulb must stay on for at least 20 minutes for longest life.
