LEDs are the only bulbs capable of using the Light Bright technology. LEDs came out in 1962 and the only color available was red and at a low-intensity however current versions are available across the visible spectrum and can be very bright.
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.
Answer: The future is bright. Answer: LEDs use less power than even fluorescent light bulbs, so they show great promise. As soon as they can be mass-produced sufficiently cheaply, they will gradually replace the currently used technologies.

Tungsten is used in filaments of light bulbs.
LED bulbs tend to be very bright and use far less power to operate making them perfect for flashlights. Halogen bulbs are also very bright and used in flashlights.
I don't think necessarily, though if you get it that bright, you might require a lot of radium, which is radioactive. High levels of radium causes cancer. More than likely, the object or coating will need to be an electrical conductor for the light energy to pass through it. But there may be some cases where something can glow in the dark bright enough to where bulbs are not necessary.
In older "tube" televisions, there is one bulb that produces light and reflects throughout the Television Housing. Newer LCD and Plasma screens use totally different technology and have no bulbs in them.
only some light bulbs will light a cigarette. a normal one wont but one of the kinds that are so bright you can't look at for very long will light it.

Those wanting softer, diffused light use frosted light bulbs. Clear bulbs give light that is brighter and suitable for everyday applications.
You use a light bulb.Such light bulbs use different types of technology; for example, the old-fashioned (and quite inefficient) incandescent bulb heats a wire, which acts as an electrical resistance, to the point where it glows.
