Which among the following is most energy efficient incandescent build fluorescent tube compact fluorescent light bulb halogen bulb?
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
A red fluorescent blu fluorescent or a tungsten-halogen light bulb would be most likely to cause a plant to wilt?
Tungsten halogen light because the graph shows that rapidly increases and doesn't go down
What type of light is a 20 watt energy saving bulb Halogen Incandescent neon or fluorescent?
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
Can you put fluorescent tubes on a dimmer switch?
Yes, as long as it is just incandescent bulb lighting connected to the track. If there is a transformer between the voltage source from the track and the light bulb (e.g. low voltage quartz bulbs) then these fixtures can not be dimmed.
What is the green efficient squiggly light bulb called?
Florescent light-bulbs CFL Compact Fluorescent Lamp
Which among the following is most energy efficient incandescent build fluorescent tube compact fluorescent light bulb halogen bulb?
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
How efficient is a compact fluorescent bulb?
about 5 times as efficient.
Which is more efficient the fluorescent bulbs or the incandecent bulbs?
Fluorescent bulb is the more efficient one as compared to incandescent bulbs.
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
What is the most energy efficient light bulb?
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
How efficient is a fluorescent bulb that emits the same amount of light as a 100w incandescent bulb?
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
What wattage halogen bulb will match a 100 watt incandescent?
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
Which type of light bulb is more efficient light bulb incandesent or an fluorescent light bulb?
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
A red fluorescent blu fluorescent or a tungsten-halogen light bulb would be most likely to cause a plant to wilt?
Tungsten halogen light because the graph shows that rapidly increases and doesn't go down
What are the best table lamps that provide good energy efficient lighting?
A table lamp with a fluorescent or LED bulb provides excellent energy efficient lighting. Almost any lamp can accommodate a compact fluorescent or LED bulb which makes any fixture more efficient.
What light bulb types uses the least energy and therefore results in fewer greenhouse gas emissions?
Halogen+++No longer. LED-based fluorescent lamps use a lot less electricity than halogens for similar light levels - much of the energy emitted by a halogen lamp is heat, although it is more efficient than the equivalent argon-filled incandescent lamp. (A halogen bulb is still an incandescent type - it simply uses a different gas filling from the conventional bulb.)
How efficient is a light bulb?
An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
