- A hardware store here recently started selling a line of halogen light
- bulbs, marketed by GTE under the Sylvania brand.
-
- According to the advertising on the box, the new bulb uses a tungsten/
- halogen capsule (apparently similar to those used in cars) enclosed in
- a second, outer glass bulb. The outer bulb glass is much thicker than
- "normal" light bulbs, and the new bulbs are much heavier than usual.
-
- I bought a few of these bulbs (at about $5 for a 100W bulb, they're on
- the pricey side), and I must say I'm very pleased. The light is much
- whiter than what you get from regular incandescent bulbs. According to
- the box, the new bulbs are about 10% brighter than conventional bulbs
- of similar wattage and are supposed to last about three times as long.
-
- I've heard concerns about UV radiation from halogen lights, but I would
- assume the thick outer glass bulb would absorb most of the UV.
-
- I ordered some of SunBox's "northern sunlight" neodymium incandescent
- bulbs yesterday; it'll be interesting to compare the two kinds of light
- side by side.
