Light Matters

Edison’s Babel: new foto

Posted in A Design A Week, Bulb Ban by studiomakelight on November 19, 2009

Testing the new Osram Halogen energy saver bulb on Babel.

These bulb are essentially normal halogen light in Edison bulb glass. It is 30% more efficient than Edison bulb because filament is enclosed in halogen gas to allow it burns better while giving out light. Since halogen light is an improved version of Edison’s invention, it gives the same kind of warm light we are accustomed to.

Halogen energy saver is closer to a single point light source than Edison bulb. As a result, the shadow is more defined (see foto below).

In comparison to CFL, I prefer Halogen energy saver. It has better quality light in terms of colour temperature and light/ shadow effect. Unlike CFLs, there is no need to buy a even more expensive dimmable version, any Halogen energy saver bulb is dimmable.

Until cleaner and more sustainable lighting technology becomes available, for better light quality, I will use Halogen energy saver because I am concerned about the toxic mercury contain in the CFL.

    Due to their filament orientation, these halogen lamps emit more lights toward the sides than traditional light bulbs than, in this case, downward. Philips’ first version, when they used linear halogens in the higher wattages, is even more extreme in this regard, and had a non-glowing electrode wire that produced a shadow line, especially noticeable in the clear version. They have since switched to G9-style capsules, too.
