Do eco bulbs have mercury?
ByMary Mazzoni. Compact fluorescent light bulbs (CFLs) use 75% less energy than traditional incandescent bulbs and last about six times longer, but it’s no secret that CFLs contain a small amount of mercury (about 4 milligrams per bulb on average).
Do EcoSmart light bulbs contain mercury?

Are energy efficient light bulbs toxic?
Compact florescent lightbulbs — known as CFLs — can deliver big savings on your energy bill. CFLs contain mercury — a dangerous toxin that can effect your nervous system. And if one breaks, mercury is released into your home.
Which bulb causes mercury pollution?
Of the lamps investigated, incandescent lamps result in the highest emissions of mercury to the environment per unit of light produced, and halogen lamps the least per unit of light produced. Compact fluorescent lamps lie somewhere in between.
How bad is mercury in light bulbs?
Mercury is essential to a fluorescent bulb’s ability to emit light; no other element has proved as efficient. As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children.
Can mercury in light bulbs hurt you?
When the tube of a fluorescent light bulb breaks, the mercury vapour inside is released into the air. Most of the mercury released from the CFL turns liquid very quickly so, shortly after the breakage, the level of mercury vapour becomes too low to cause any harm to adults, even those who are particularly sensitive.
Where is the mercury in a CFL bulb?
glass tubing
CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. When a bulb breaks in your home, some of this mercury may be released as mercury vapor.
What bulbs contain mercury?
Mercury-containing light bulbs include:
- fluorescent bulbs, including compact fluorescent light bulbs (CFLs);
- high intensity discharge (HID) bulbs, which include mercury vapor bulbs, metal halide and high-pressure sodium bulbs, and are used for streetlights, floodlights, parking lots, and industrial lighting; and.
Do LED light bulbs have mercury?
LEDs use significantly less energy than even CFLs, and do not contain mercury. And the copper found in some LEDs can pose an environmental threat if it accumulates in rivers and lakes where it can poison aquatic life.
How much mercury is in a light bulb?
An average of 4 milligrams (mg) of mercury is in a CFL. A mercury thermometer may contain about 500 mg of mercury. About 500 mg to 700 mg or less of mercury is considered a small spill. Some CFLs may contain as little as 1.4 mg to 2.5 mg per light bulb.
