看了这篇文章，提醒一下用CFL最好远离至少30cm
fluorescent lights produce UV when the mercury vapour is 'excited' by the
electrical current. However, the amount of UV produced is so small that it
is not considered hazardous to your health. The results of the Health Canada
study showed that, when either CFLs or regular light bulbs (incandescent)
are used at a distance of 30 cm or more, UV emissions do not present a
health risk to the general population. Health Canada recommends that
people keep this minimum distance between themselves and any light source.&#
160; When CFLs or regular light bulbs are used daily at 30 cm, exposure
should be limited to no longer than 3 consecutive hours.
Although CFLs are considered safe to use, here are some steps you can take
to further protect you and your family:
Always handle CFLs carefully when installing and removing them.
Check with your municipality to see if CFLs can be recycled in your area.
Recycling them means that the small amount of mercury they contain will not
end up in the environment.
If you have skin sensitivities to UV, or have Lupus or another auto-immune
disease that makes you sensitive to UV, you can take these steps:
Buy CFLs that are marked low UV.
Buy CFLs that have a glass cover already added, which will help further
filter out UV radiation.
Use additional glass, plastic or fabric materials in your lighting fixtures
to act as UV filters.
Increase the distance you are from the CFL, as this will reduce the level of
UV exposure. |

射的高频成份越多，卤素灯温度比白炽灯高多了，需要有特殊的滤除紫外线的玻璃。以
前那种200～300瓦的落地灯，往天花板上打的，灯管比圆珠笔稍小的就是卤素灯，有一
块石英玻璃把紫外线吸收了。
