Yes, although cost issues may prohibit. I've seen companies that make LED/lightbulbs.

Can you reverse polarity on a light?
Yes, with a retroreflector. One form of a retroreflector is 3 mirrors all mutually perpendicular like the corner of a cube.
What is the lumen of 23 watt CFL?
A 23 watt cfl will give off roughly 1600 lumens. However that is only within a few inches of the bulb.
How can you use the word efficiency in a sentence?
The cfl's proved total efficiency.
Why choke is not used in CFL bulbs?
CFLs have two main components: a magnetic or electronic ballast and a gas-filled tube (also called bulb or burner). Replacement of magnetic ballasts with electronic ballasts has allowed the development of smaller lamps directly interchangeable with more sizes of incandescent bulb. Electronic ballasts contain a small circuit board with rectifiers, a filter capacitor and usually two switching transistors. The incoming AC current is first rectified to DC, then converted to high frequency AC by the transistors, connected as a resonant series DC to AC inverter. The resulting high frequency is applied to the lamp tube. Since the resonant converter tends to stabilize lamp current (and light produced) over a range of input voltages, standard CFLs do not respond well in dimming applications and special lamps are required for dimming service
Does it matter if the voltage leads the current or the current leads the voltage?
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
How much is it for lighting?
Lighting is not one of the major electrical costs in a house, especially if CFL (compact fluorescent lamps) or LED bulbs are used. If lighting costs are an issue, get rid of incandescent bulbs and halogen bulbs. CFLs are cheaper and nearly as efficient as LEDs.
What can one use CFL lamps for?
CFL stands for Compact Fluorescent Lamp, and they are an energy-efficient alternative to incandescent bulbs. CFL lamps can be used to replace these bulbs, and they can be placed both indoors and outdoors.
When will be the Mercury lamps will be stopped in market?
If you are referring to fluorescent and CFL lamps, it can never be totally eliminated. These are mercury vapor arc lamps using a phosphor to turn the UV to visible light. They have reduced the mercury dramatically, but it can't be totally eliminated. If all fluorescent and CFL lamps were banned and lighting was all converted to LED then use of mercury could be stopped. However most LED lamps cost at least ten times what CFL lamps cost.
Why do you use CFL insted of electric filament bulb?
The power consumption is lower on CFL lamps. Result, you save money operating them.
Is there a dimmable CFL bulb that can be used with an electronic dimmer?
Compact fluorescent bulbs used to be all or nothing. They couldn't be dimmed. Most cfl lamps (bulbs) are this kind. However, special cfl bulbs are now being marketed, at a higher price, that can be dimmed by a normal dimmer switch previously used for incandescent bulbs. However, not all dimmer switches work with these newer dimmable cfl lamps.
Who created the cfl?
No one created the CFL instead there was a group of people who came up with the idea
Do any car replacement lamps use CFL bulbs?
There are not currently any car replacement lamp that use CFL bulbs. I wouldn't be surprised to see them or something similar in the near future.
How much power does a 250 watt hps light use an hour?
compare to different lamps mv lamp,hpsv lamps & cfl lamp these are how mush energy comsumed for 225w lamp
What is CFL mhl and hpmv lamps?
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
Is it worth to use LED lights instead of CFL or Incandescent light bulbs?
I guess yes, because LED is just tinny light emmiting diode which consumes very less energy as compare to CFLs or Incandescent lamp and hence it leads to save our electric bills as well. CFL also a new concept of lightning but LEDs are the latest ones & performs much better as compare to Incandescent lamp.
What does a CFL with choke mean?
A CFL is a Compact Florescent Lamp. Compact florescent lamps are more complex than a traditional lightbulb, and the circuits inside the CFL create electrical "noise" in that can affect other devices. The choke is a coil or inductor that is designed to filter out the noise to reduce it's interference with other devices.
Last week I attended a stage show in my city I noticed that whole stage was decorated with compact fluorescent lights lightning. What I want to know is the number of watts that CFL lamps use?
In a stage show it needs various types of CFL and Sylvania offers comprehensive range of high-efficiency fluorescent lamps in various lengths, diameters, wattages, colours as well as lamps for a wide range of specialist applications. Only watts doesn't matter in stage show.
