Spent fluorescent lamps are typically packaged prior to transport to a recycling facility in one of three ways: boxed for bulk pickup, by using a prepaid lamp recycling box, or crushed onsite before pickup. A fluorescent lamp crusher can attach directly to a disposal drum and isolate the dust and mercury vapor.
In the 1970s, Thorn Lighting introduced an energy-saving 8 ft retrofit tube in Europe. Designed to run on the existing 125 W (240 V) series ballast but with a different gas fill and operating voltage, the tube operated at only 100 W. Increased efficiency meant that the tube produced only 9% lumen reduction for a 20% power reduction. [ 7 ]
Several countries have specialised recycling or disposal systems for fluorescent bulbs. According to the U.S. Environmental Protection Agency (EPA), the amount of mercury contained in a compact fluorescent lamp (about 4–5 mg [20]) is approximately 1% of the amount found in a single dental amalgam filling or old-style glass thermometer.

[32]: 20 The efficacy of fluorescent tubes ranges from about 16 lumens per watt for a 4 watt tube with an ordinary ballast to over 100 lumens per watt [51] with a modern electronic ballast, commonly averaging 50 to 67 lm/W overall. [52] Ballast loss can be about 25% of the lamp power with magnetic ballasts, and around 10% with electronic ballasts.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs.
230 V sizes: PAR 16, 20, 30, 38, 56 and 64 Available in numerous spot and flood beam spreads. Like all light bulbs, the number represents the diameter of the bulb in 1 ⁄ 8 of an inch. Therefore, a PAR 16 is 51 mm (2 in) in diameter, a PAR 20 is 64 mm (2.5 in) in diameter, PAR 30 is 95 mm (3.75 in) and a PAR 38 is 121 mm (4.75 in) in diameter.
'9-1-1: Lone Star' actor Rob Lowe's new game show 'The Floor' revealed a first look trailer and the news it will premiere on January 2, 2024.
The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...
