- How high is the ceiling? The higher, the more the light shines. But if it is too high, it is lost again.
- White walls or other color? A white wall reflects better.
- How big is the room? The larger the room, the stronger the light source must be.
For me, the ceiling is relatively high (~ 2,80m), in a space of about 5x5m, with white walls. As a result, the lamp is sufficiently bright enough and instead they 300W verbrät just only 13W. I'm gone over, thus compensate for the reduced brightness to turn on another lamp - an LED desk lamp. This consumes 10W.
Together, the lighting is great and always be the result of only 23W consumption to 300W of earlier against.
Note: I had to modify the heat shield of floodlight easily. This is necessary, unfortunately, in many lamps and results from the design of powered ceiling lamp. One should be clear that with such an action loses the guarantee with a new uplight. In addition, the heat shield most cable and live parts of the lamp covers. Who it does not trust, who should leave it alone. Also to note: to remove the heat shield is completely MMN not a good idea. So be open some components. In addition, the LED light source generates quite a bit of heat and radiate downwards.
Conclusion: A 150W halogen lamp will definitely replace this lamp, but even brighter lights can be according to the requirement, replaced. The power consumption is top and the luminosity of more than satisfactory.
