Any efficient one can. The inefficient ones are those that turn most of
their fuel or electricity into heat, and only a small part of it into light.
A few efficient light sources are:
-- CFL bulbs
-- fluorescent minerals
-- fluorescent light tubes
-- the hind end of fireflies

What color is at the warm end of the visible spectrum and what color is at the cool end?
warm is red and cool is blue
What is cool light?
The light which comes from Florescent tubes is called COOL LIGHT. Another example is L.E.D. lights as well. The light other than Halogen Lights is cool because Halogen Light is warm light.
Does ultraviolet rays in electro magnetic radiation causing certain substances to fluoreste?
Yes. The cool thing about this phenomena is that you can't see ultraviolet light, but it often causes EM radiation in the visible spectra, so it's kind of like the visible from the invisible...spooky.
Are compact fluorescent bulbs cool to the touch?
Relatively cool, yes, especially if you compare them with incandescent lightbulbs.
Why is an incandescent lamp cool to the touch when it gives off heat?
An incandescent lamp is not cool to the touch unless it is an extremely low wattage. Heat given off by incandescent lamps is one of the drawbacks of the lamp. Total overall efficiency is reduced by the wasted heat.
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
yes
When was Cool Touch created?
Cool Touch was created in 1990.
What are some cool plant related science fair projects?
test plants with different light sources
What is the common difference between the tube light and CFL bulb?
regular light bulbs have certain elements in them, that when electrified, emit radiation in the infrared. this is why regular bulbs get hot. when we turn on the light we need light, not heat. that's why these are wasteful. they're producing all this stuff we don't need. CFL bulbs have elements that when electrified, emit mainly visible light, what we need. also why they tend to remain cool to the touch.
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.

What does amber feel like?
Smooth and cool to the touch.
does Honeywell HZ-725 Cool Touch Whole Room Heater comes with remote?
The Honeywell HZ-725 Cool Touch Whole Room Heater does not come with a remote.
What is the difference between a cool touch heater and a mica panel radiator heater?
Cool touch heaters are made of ceramic and aree very safe, while mica radiators are hot to the touch but produce much more heat.
