Buying a light bulb used to be easy
Buying a light bulb used to be really easy, but that changed with the arrival of energy-saving models. Here is a feature list:
- Brightness.
Unfortunately, the lumen values are not linear, especially from 2,000 Lumen. I don't know the maths. If you can help, please drop me a line. This is the table I have been using for reference:
Incasdencent Watt | Lumen | LED Watt | Energy-saver Watt |
---|---|---|---|
40 | 400 | 8 | |
60 | 720 | ||
80 | 1,000 | 20 | |
100 | 1,200 | ||
150 | 1,700 | ||
200 | 10,000 |
- Color temperature. 2700K is best. 3000K might be described as "soft, warm white", but you'll notice the difference.
- Turn-on speed.
- Lifespan.
- Cycling endurance.
- Clear or frosted glass.
- Noise.
- Dimmable.
- Physical robustness.
- Operating temperature.
