How many lumens are in a 20 watt halogen bulb?

Answer 1

1600 Lumens

Answer 2

The lumen output of the bulb should be determined by measuring the Lumens exiting the fixture that it is installed in. The reflector, lens and housing will all affect the the amount of "light" that exits the fixture to reach the space you are intending to illuminate. Bulbs will vary and Lumens will vary based upon the voltage. A typical 12V 20W Halogen bulb will yield about 180-220 lumens depending on the lens (clear vs. frosted) and the reflector type. Lumens will drop as voltage goes below 12Volts as the design voltage is specified in order to "excite" the halogen gas as it reacts with a tungsten coated filament. If the voltage isn't high enough the filament won't reach it's design temperature and the light won't burn as bright as it was designed to. a lone bulb will yield up to 280-300 Lumens with now housing, lens or fixture but it is also very dangerous due to the heat hazard.

Answer 3

Bosch Automotive Handbook, 7th Ed. says the high beam of a 12V 55W H1 halogen bulb is 1550 lumens, so a 20W halogen would be about 560 lumens. The exact amount of lumens will vary from one brand to another.

Answer 4

A 20 watt halogen bulb draws about 0.2 amps. A simple rule of thumb in considering wattage is that 100 watts draws about 1 amp.

Answer 5

350 lumens. That's from the specs on most of the 20 watt G4 halogen bulbs on the 1000bulbs website.

Answer 6

A 20-watt halogen bulb typically produces around 200-250 lumens of light.
