DC Lights
|
DC Compact Fluorescent Lamps These Montana Lights use about 1/4 the electricity for the same brightness of incandescent bulbs and last about 10 times longer. Instant starting with no flicker. Standard screw base for easy replacement of power hungry incandescent bulbs. The SE, DE and TE tubes have 4 pins not 2 pins and are made for electronic ballasts. Bulbs rated 10,000 hour life, ballast rated 45,000 hours with normal usage. Life will be less when operated for short on time cycles. |
|
Compact fluorescent bulbs are about four times brighter than incandescent bulbs. These lights screw into standard size sockets and must have the center tip wired for positive (+) and the outside threaded part wired for negative (-). Use large enough wire so the bulb will not have a voltage drop when starting or bulb will have reduced life. 12 volt systems may require 10 gauge copper wire. |

Compact Light Ballast Base - uses low cost replaceable bulb
Lamps are available with a one piece bulb and base. These waste resources. When the bulb quits, you have to throw away the whole thing - bulb and ballast. The units with a replaceable bulb are more cost effective. Efficient ballast is in base. Use in table lamps and other lights with sockets. The center contact on ballast is positive. The SE tubes 5, 7, 9 and 13 all fit the same ballast base. Overall length: SE5 is 6-1/4”, SE13 is 9”. The TE 13 or TE 18 tubes fit their same ballast base. Base is 2” x 3-1/8”. Overall length: TE13 is 6-1/2”, TE18 is 6-3/4”. Made in USA by Montana Light. Tube is not included, see tubes below for ordering the size you need.

DC Incandescent Light Bulbs |
|
Fluorescent lights are 3-4 times more efficient than incandescent lights, so use them in lights that are on the most. This will save energy and you will have more energy available for other loads. Incandescent lights are okay for infrequently or briefly used lights, such as closets or hallways. Fluorescents used in this manor will have much less than normal 10,000 hour life. Incandescent bulbs (and LEDs) will never have RF noise that could interfere with some radios. Halogen bulbs are about 30% brighter than standard bulbs and produce a whiter light. They can explode if water splashes on the hot bulb or if they are operated on higher than normal voltage. Operate within + or - 10% of rated voltage. Low voltage can darken bulb. |
|
Standard Bulbs Low cost with standard base. Not as efficient as Halogen bulbs. About 30% brighter than 120 volt AC bulbs. Nice for seldom used lights or short on time use. Packaged 4 to a box. Prices shown are per bulb. |
