Make a standard yellow incandescent light look white?

Question

Is there some type of filter, gel sheet or fabric which i can put in front of a normal light bulb to make it look white? OR is there anything which i can do to make the light white?

Answer 1

You can buy incandescent bulbs designed for a high color temperature and good color balance. Photographic floodlights are the most common. You can buy photographic filters designed to compensate for incandescent color balance. But the energy they absorb is wasted. You can buy full spectrum compact fluorescent lamps. Their color balance is good and they are also energy efficient. You can add separate blue lights to compensate, but unless they are fluorescent, they are also inefficient. Theatrical lighting does this.

Answer 2

There are two separate issues in play here. First is wattage. A 23 watt CFL (100 watt equivalent) poses no risk in a 60 watt max fixture when only wattage is taken into consideration. The second issue is then the deciding factor - heat generation. Most lamp sockets are actually limited in wattage due to heat generated by a standard incandescent bulb and the damage that heat could do to the wiring (most lamp wire is not rated for high temperatures). While a CFL generates less heat overall than an equivalent incandescent, the heat in a CFL is concentrated at the ballast which is located near the socket. Depending on the brand of the CFL bulb, the integrated ballast could actually generate more heat at the socket than a 60 watt bulb. Also, the ballast is heat sensitive itself. If the heat cannot dissipate fast enough, the ballast can overheat and shorten the life of the CFL considerably. With that in mind, a CFL installed in an open fixture with good air flow around the socket should not have a problem with the increased CFL equivalent. Enclosed fixtures are a different matter. Because of the inadequate air flow, CFLs should be limited to their incandescent equivalent in such fixtures. Many CFLs even have warnings stating not to use them in enclosed fixtures. As to the overall question: Use at your own risk.

Answer 3

You would be better off to just get some fluorescent bulbs. You would have your natural light, save electricity, and generate less heat. Most of the energy used in a normal bulb goes into heat rather than actual light, which is a huge waste in the end.

Answer 4

Not really. White is the combination of all wavelengths. Gels block certain wavelengths to make a light contain only a certain wavelength.

You can't get a combination of frequencies by removing some from the original light.

Get a 6500k CFL bulb or something.

Answer 5

no paint will work but it wont be as bright
a fluorescent lamp works by absorbing the lamps ultra violet light in a powder coating the inside of the tube the powder coating then fluoresces or shines white

Answer 6

umm change the bulb to a flouresent cool white or one of the true color bulbs

Answer 7

Paint it.
