The suggestion was that in other portions of the visible light spectrum (red I suspect, amber perhaps) LEDs may have a slight energy efficiency advantage over fluorescents.
Halogen bulbs are typically bright, sometimes 500 watts or more.
And they give off a lot of heat.
Would a 40 watt halogen bulb be more energy efficient than conventional tungsten?
What kind of bulbs do you use?
Do you like them? | We use mostly compact fluorescents. We love them. They last much longer than conventional bulbs, give off light that seems closer to natural and save on our electric bill.
I don't know anything about LEDs for general lighting. Maybe someone else does.
We have one halogen lamp. It does give off a lot of heat. I have used it mostly when doing photographs to create indirect lighting. ( By bouncing the light off the ceiling.)
I also have a light therapy floor lamp. It is hotter than a standard flourescent but cooler than halogen. I really like it for doing close work like sewing. It is supposed to give off light identical to sunlight. I can't say whether it has affected my mood any but it certainly has helped thread my own needles.  |
