What does PL-L Mean?

PL-L Philips Light Bulbs are compact fluorescent plug in light bulbs. Each have 4 pins that plug in to your fixture and are configured in a straight line. PL-L stands for "Philips Linear-Long."

These bulbs have an average rated life at 15,000 (36 watts and under) and 20,000 (40 watts and above) hours making them a significantly more effecient light bulb to use. PL-L light bulbs come in the following wattages: 18, 24, 36, 40, 50, 55 and 80. Most wattages are available in 830, 835 and 841 color ranges. The 55 watt only comes in an 841 and 950 color.

With these bulbs it is possible to interchange wattages. The bases and thus the ballast that powers these bulbs are all the same which allows for easy wattage substitutions.
