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 else can I help you with?
What color is at the warm end of the visible spectrum and what color is at the cool end?
The warm end of the visible spectrum is red, while the cool end is violet.
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.
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.
Can you see a white dwarf?
Yes you can see a white dwarf star. but you will need a powerful telescope. The nearest white dwarf to us, is Sirius B at a distance of 8.6 light years. It was first discovered using a 18.5-inch (470 mm) aperture telescope.
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.
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
A very hot light bulb produces more blue light than a light that is cool to the touch. As the temperature of the bulb increases, it emits higher energy photons, which are in the blue-violet part of the light spectrum. Cooler bulbs emit more red and infrared light.
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 criterion indicates that you are heating a solution with a cool flame?
A cool flame produces little to no visible light or soot, and may be difficult to see. The flame typically has a blue coloration and is nearly invisible in daylight.
What color is at the warm end of the visible spectrum and what color is at the cool end?
The warm end of the visible spectrum is red, while the cool end is violet.

What does cct mean?
CCT stands for Correlated Color Temperature, a measure of the color appearance of light sources. It indicates whether a light source appears more warm (yellowish) or cool (bluish) in color.
What will happen to the light bulb when you switch off the electric circuit?
When you switch off the electric circuit, the flow of electricity to the light bulb will stop, causing the filament in the bulb to cool down and stop emitting light. The bulb will go dark until the circuit is switched back on.
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.
What does amber feel like?
Smooth and cool to the touch.
What is the difference between lumens and kelvin when it comes to measuring the brightness and color temperature of light sources?
Lumens measure the brightness of a light source, while kelvin measures the color temperature. Lumens indicate how bright the light is, while kelvin indicates the color appearance of the light, such as warm or cool.
