What is the hottest light bulb?

Answer 1

There are two main types of commercially available energy-efficient light bulbs. These are LEDs and CFLs. Both are better than traditional incandescent light bulbs when it comes to energy efficiency

The efficiency of light bulbs is calculated by comparing the amount of light produced to the amount of energy consumed:

• LED bulbs produce 90 to 112 lumens per watt.
• Compact fluorescent lamps or CFLs produce 40 to 70 lumens per watt.
• Traditional incandescent bulb fixtures only produce 10 to 17 lumens per watt.

There are other considerations:

• Compact fluorescent light bulbs have a life span of eight to 10 years and cost about $4 per bulb.
• LED bulbs last up to 40 or 50 years but can cost over $306 per bulb.
• CFLs contain Mercury which may require special handling for disposal while LEDs do not.

Answer 2

The amount of light produced is measured in lumens, while the electric power used is measured in watts.

An old-type 100 watt incandescent bulb produces about 1200 lumens. The same amount of light can be produced by a 70-watt halogen bulb, a 20 watt CFL bulb or a 15 watt LED.

The power that is not turned into light is turned into heat instead.

Answer 3

Bulbs with filament would produce larger amount of heat compared to fluorescent lamps

Answer 4

the largest wattage of course...dummy
