Almost time to change the light bulb
He suggests sticking with well-known brands and bulbs that carry the Energy Star designation, which means they meet standards for energy efficiency and overall quality. (Halogens emit light in all directions, for instance, while most LEDs are unidirectional. Tips for buying bulbs in the complex world to be ushered in by the new lighting law. Lighting technology, particularly for LEDs, is improving rapidly, and prices are dropping steadily, so it makes more sense to replace bulbs as needed. BRANDS COUNT: There is wide disparity in bulb quality. "For a lot of offshore manufacturers, the performance is uncertain," said Craig A. Bernecker, director of Philadelphia's Lighting Education Institute. STUDY UP: There are more types of bulbs, and more yardsticks by which to compare them. Easing into the light.

Two Level Light Switch Circuit?
Halogen lamps are manufactured with enough halogen to match the rate of tungsten evaporation at their design voltage. I have a halogen desk lamp with an on-off-on rocker switch. Increasing the applied voltage increases the rate of evaporation, so at some point there may be insufficient halogen and the lamp goes black. The life span on dimming depends on lamp construction, the halogen additive used and whether dimming is normally expected for this type. There are many situations where halogen lamps are dimmed successfully. I was wondering if anyone had an idea for a circuit I could hook up to one switch to make the lamp at half brightness. However, lamp life may not be extended as much as predicted. At much lower voltages, the bulb temperature may be too low to support the halogen cycle, but by this time the evaporation rate is too low for the bulb to blacken significantly. I know I could just put a resistor in series with it, but do not know how to measure the resistance of a......
Halogen Desk Lamp FAQ
I have a halogen desk lamp that occasionally hums. What can I do about it?My FIL gave me this lamp because the humming bothered him. I tested it and couldn't hear it. Then it started humming. I unplugged it and plugged it in later and it no longer hummed. I have since tested this out several times and sometimes it hums and
That is what a number of those lamps do. The cheaper ones have magnetic ballasts. The hum is something they do. The only way to eliminate it is to get an electronic ballast, but may not be worth the cost. Flicking it on and off 50 times won't do much
