    Energy saving light bulbs are dangerous closer than several dozen centimerters.. So, they are OK for roof lighting, but are NOT okay for bedside lighting.

    As for LED: they are OK (more than OK http://www.ted.com/talks/harald_haas_wireless_data_from_every_light_bulb.html) as long as you take into consideration that the backside is really hot.

    Several new LED 'lightbulb' designs have surfaced within the last few months, with better heat dispersion technology.

    I agree with Zephram Farrington I am currently using the LED bulbs and I'm quite happy with the light color and as far as I know my skin is fine. :)

    Zephram Farrington and Gunther Cox Thanks! Dare to share some links? The main issue for me is not heat dispersal, it is heat creation. Any progress on this?

    David Latapie This is the type that I am using: http://www.amazon.com/LED8E26A1930K-3000K-Dimmable-Watt-Lamp/dp/B005FG51XA

    The price makes some people back off and not buy these but the thing is that the only reason that it is higher priced is because the manufacturer has to be able to compete with other light bulb makers. If they sold them for less they wold go out of business because the LED bulbs can last for over four years! I am sitting under the light from one now and the bulb is just about skin temperature when I touch it. 

    Also, regular bulbs which last only a few months run at about $9.00 so it all works out to be about the same price for bulbs in the end. You just pay a lower electric bill.

    I will try, David Latapie, but I am on mobile and might not be able to track them down. As I recall, the recent innovations were primarily in heat distribution/dispersal, not heat creation, but I may have missed something.

    Gunther Cox Thank you, but my point whas that led are cold on the frontside (the lighting side - that is why this is skin temperature), but actually hot on the backside (the part you don't see). This matters if you plan to avoid any kind of ventilation or put them close to a flamable object (like papier), I'd say.

    and LEDs are hardly great either  http://ceolas.net/#li15ledax
    dont confuse color temperature with their uneven spectral quality
    The pushed white LEDs are basicaly like CFLs given their use of phosphorescent coating to spread  light
