400 watt metal halide fixtures can be purchased at various sites on the internet. Some sites that you may want to try out include the following: Amazon and Home Depot.
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.
Yes assuming the ballast is also for a metal halide lamp.
Yes.
It depends......perhaps 7400 to 8500 initial lumens degrading to 5400 lumens.
The light bulb needs to match the ballast in the fixture.
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
For the amperage of a metal halide fixture look for the nameplate which can be found on the side of the ballast. There it will tell you what the amperage of the fixture draws. Knowing what one fixture draws will allow you to size the lighting circuit for wire and breaker sizes.
No, the ballast's output is not matched to operate a fluorescent bulb.
Yes, the ballast is an intricate part of the fixture that the lamp screws into regardless of what size wattage the lamp is.
6000lm
Yes assuming the ballast is also for a metal halide lamp.
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
It will power two 400 watt lamps.
At the basic level, you're looking at: * Circuit Protection (fuse or circuit breaker) * Cabling * Mounting hardware (for the light fixture itself) * Within the fixture; A socket, bulb, bulb protection (cover, or sheild)
Yes.
It depends......perhaps 7400 to 8500 initial lumens degrading to 5400 lumens.
