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.

 

Edison replacement contender: LED

Posted in Bulb Ban by studiomakelight on November 13, 2009

LED (light emitting diode) gained a lot of public attention in the last few years. It is not a new technology though, considering it has being around since 1962. But the technology did get upgraded, thanks to all the money brought in by the attention.

In the past few years, LED has progressed in several ways, colour changing and range, size and shape, brightness, cost and also supporting technology like cooling and power supply unit. And we have all heard enough from the media to know that LED somehow consumes less energy(how much really??).

From my research so far, if LED is to compete with CFLs to replace Edison bulb in the mass market, it is the brightness, cooling and cost issues that need a few more major break through.

On the aesthetic side, even though, all the contenders below try to simulate the same classic Edison bulb form, they just don’t look as good. It’s might be better if manufacturers just work come up with a new form for LED bulb all together.

The following are 4 LED bulbs currently available as Edison bulb replacements.

1- Pharox 60 from Lemnis Lighting (6W energy consumption, output brightness=60W bulb, cost: $39.95)
