No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
No, the ballast's output is not matched to operate a fluorescent bulb.
No, a fluorescent bulb does not emit the same amount of heat as a metal halide bulb of the same wattage.
It depends......perhaps 7400 to 8500 initial lumens degrading to 5400 lumens.
as long as the sockets for th bulb are the same and it is not a high pressure sodium or metal halide light
Make sure you are using a metal halide bulb and the ballast is matched to the wattage on the bulb. These both must be correct.
A halogen bulb is a traditional tungsten filament bulb filled with a noble gas that gives off a soft, yellowish light. In a metal halide bulb, the light emitted is bright white or even bluish. They have a longer life than halogen bulbs, but their brightness can diminish over time.
The light bulb needs to match the ballast in the fixture.
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
A metal halide ballast works just by transforming the line voltage into much more useful voltage to the metal halide, and by regulating the current so that the bulb will have its useful life at the most.
You need the appropriate ballast for either of these bulbs to make them light.
They are most likely a type of metal halide bulb. <<>> The above answer bulb has a bright white light output. If the light output has an orange look about it then the bulb is a high pressure sodium lamp.
