How Many Lumens Is A 250 Watt Metal Halide Lamp

A type of high intensity discharge hid lamp this light is typically used in high bay lighting fixtures in warehouses parking lots and hangars because of their high lumen output.

How many lumens is a 250 watt metal halide lamp.

Let s compare that with our 150 watt retrofit unit. The reality is that they come in a large variety of options. φ v lm p w η lm w watts to lumens calculation. Mercury containing products sold into the state of wa include an environmental handling charge of 95 each.

Metal haliod and high pressure sodium. Energy saving lamps have high luminous efficacy more lumens per watt. 250 400 and 1000 watt. It is not uncommon for metal halide and high pressure sodium bulbs to have lost up to 50 of its initial lumens after only 5000 hours of life.

So calculating lumen efficiency for metal halide. Up to 100 lumens per watt. A 400 watt mercury vapor light bulb produces roughly 23 000 lumens. Please note that metal halide lamps cannot be operated without a ballast.

Lumen rating sylvania metal halide lamps. What is hard to cross in is that metal halides actually start out at very high efficiencies. Metalarc supersaver lamps are designed as energy saving replacements for stan dard lamps. Most large fixtures use metal halide bulbs.

These bulbs produce a high lumen output for bright light in commercial settings like street lights parking lots or warehouses. 36 000 lumens 455 watts 79 12 lumens watt. In comparison to a 400 watt metal haloid and or high pressure sodium not as good. The 950 watt supersaver lamp is a direct retrofit for existing 1000 watt products.

1000w metal halide fixtures can produce. The metal halide lamp is a third generation made of various metal halides based on a high pressure mercury lamp. These 250 watt metal halide bulbs come in horizontal base up and universal burn operations to give you plenty of application options. Long life up to 20 000 hours for 360 and 400 watt lamps.

How many lumens does a 1000 watt metal halide produce. A new metal halide bulb can get almost 100 lumens to watt. Yet these bulbs are rated for 20 000 hours. 23 250 lumens 150 watts 155 lumens watt.

Commonly a 250watt 400 watt or 1000 watt. The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w. The metal halide lamp is an ac power source that produces an arc discharge luminous discharge lamp in a mixed vapor of mercury and a rare metal halide. Almost double of metal halide.
