    CFLs are a good idea and the only thing you can buy where I live. The downside is that their cost is still quite high and my experience is that their life is far less than is toted. Another drawback is "luminance Latency". I'm considering replacing all my downlights with LEDs. I think there is still a lot of scope for LED (semiconductor) technology to be a main light source for domestic use.

    True, CFL life is less than advertised but the good ones, and some of the less than good ones, will last long enough and reduce operating cost enough to way more than offset the higher initial cost. The drop I saw in my electric bill after I switchedwas considerable more than the cost of the CFLs

    There is no doubt that LEDs are going to replace incandescents and all forms of fluorescents, including CFLs, someday. However, same as CFLs when they first came out, there is a lot garbage hiding the good ones. LEDs will really take off when we start seeing more fixtures being designed specifically for LEDs, with built in voltage control circuitry instead of using LED bulbs with their own control circuitry designed to replace older forms of lighting. Another innovation that would make LEDs even more practical would be to start wiring buildings with regulated low voltage lighting circuits.

    I recently saw a fishing cap, (basically a baseball cap but for fishing) and it had leds on the rim activated by a invisible press switch in the peak,

    it was so you could tie your hooks etc without scaring the fish with too much light when night fishing, (bit pointless in the day!).

    i thought they would make great reading lights too, and if you read in bed they would double as a nightcap so win win

    keeping it light colin.

    You are only exposed to the mercury if you smash the bulb and then eat the shards, or grind them into your flesh. Bulbs with mercury in them are quite safe unbroken.
    So are unbroken thermometers with mercury in them, but they havent made any in years!

    Time for me to stock up on 40's and 60's. The most-used bulb in my house are 40's in desk lamps and table lamps. I've already got a plastic storage tub full of 75's and 100's.
