All lamps will give off UV but incandescent lamps will give-off unmeasurably small amounts. Discharge lamps essentially all contain Mercury and mercury in the discharge gives off UV. However, most lamps are enclosed in UV-absorbing glass, either as primary containment or as an outer enclosure (bulb), so very little gets beyond the outer bulb. If any lamp emits more then almost no UV, it has to be marked (R in the US), and a warning given that it cannot be used in an open fixture - in other words, it must be used behind a UV absorber (usually what is called soft glass - similar to normal window glass).
What else can I help you with?
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.
True or false a planet is a body that gives off light of it owns?
A planet only reflects light from a star like our Sun. Earth is a planet and from experience it does not shine. Stars give off their own light.
Suppose you have a number of light bulbs connected on a circuit with each bulb on a separate branch what happens if one of the bulbs burns off?
As they are connected in parallel (each has its own branch) the remaining bulbs keep shining exactly as they did before.
Does luminous light give off heat?
yes
What does the sun a bOnfire and a street lamp has in common?
They all contain Sodium which gives off a unique orange glow when heated.
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.
Which light bulbs give off all the colors of visible light?
Incandescent bulbs or if you prefer, plain old fashioned light bulbs, the ones with a filament (the bit of wire inside) that gets very hot and gives off light. They tend to give off a bit more at the red end of the spectrum, particularly the lower power ones but they do give off all the colours. Some run the filament at a sufficiently high temperature to give a pretty balanced white light. Most of the modern energy efficient bulbs give off light at a limited number of frequencies but much more light per watt of power that goes in.
How does a xenon bulb compare to halogen?
Xenon bulbs give off whiter light than Halogen bulbs, which give off a more yellow tint. Also, Halogen bulbs give off more heat than Xenon bulbs.
What three things give off light and heat?
The sun, fire, and light bulbs are three things that give off light and heat. The sun is a natural source of light and heat, fire is created through combustion, and light bulbs produce light and heat through electricity.
Which light bulbs give off very little energy as infrared rays?
LED light bulbs give off very little energy as infrared rays compared to incandescent light bulbs or halogen light bulbs. LEDs are more efficient at converting energy into visible light, resulting in lower heat output in the form of infrared rays.
List of things that give off light?
Sun, moon, stars, light bulbs, candles, fireflies, and glow sticks.
What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
What objects give off light because of high temperature?
Objects such as stars, light bulbs, and burning candles give off light due to high temperature. When an object is heated to a high temperature, it emits electromagnetic radiation in the form of visible light.
What planet does not gives off its own light?
Planets dont give off light therefore all planets dont give off its own light
How does the light bulb improve people's lives from the 19th century?
So their houses and streets can be brighter because light bulbs give off more light than candles
What is a form of electricity that can produce heat and light?
An example of electricity that can produce heat and light is incandescent light bulbs. These bulbs use electricity to heat a filament inside, causing it to give off light and heat. The filament emits light as a result of being heated to a high temperature.
Why are most light bulbs white not clear?
Lightbulbs are frosted white to reduce glare. The clear bulbs give off more light, but the light is harsher to the eye, making "spots" when viewed without a shade. The frosting inside the bulb eliminates this problem.
