How Many Lumens Is A 250 Watt Metal Halide Lamp

Mercury containing products sold into the state of wa include an environmental handling charge of 95 each.

How many lumens is a 250 watt metal halide lamp.

Please note that metal halide lamps cannot be operated without a ballast. 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. Let s compare that with our 150 watt retrofit unit.

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. 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. A new metal halide bulb can get almost 100 lumens to watt. A 400 watt mercury vapor light bulb produces roughly 23 000 lumens.

The 950 watt supersaver lamp is a direct retrofit for existing 1000 watt products. The 360 watt supersaver. What is hard to cross in is that metal halides actually start out at very high efficiencies. Long life up to 20 000 hours for 360 and 400 watt lamps.

23 250 lumens 150 watts 155 lumens watt. These bulbs produce a high lumen output for bright light in commercial settings like street lights parking lots or warehouses. Yet these bulbs are rated for 20 000 hours. What is a metal halide lamp.

Remember the golden rule. Metal haliod and high pressure sodium. 250 400 and 1000 watt. Almost double of metal halide.

φ v lm p w η lm w watts to lumens calculation. How many lumens does a 1000 watt metal halide produce. Up to 100 lumens per watt. The metal halide lamp is a third generation made of various metal halides based on a high pressure mercury lamp.

So calculating lumen efficiency for metal halide. Most large fixtures use metal halide bulbs. A metal halide mh lamp is an electrical lamp or bulb that produces light by creating an electric arc combining a gaseous mixture of vaporized mercury and various metal compounds bromine or iodine. The reality is that they come in a large variety of options.

Metalarc supersaver lamps are designed as energy saving replacements for stan dard lamps. Lumens to watts calculator watts to lumens calculation. Energy saving lamps have high luminous efficacy more lumens per 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.

1000w metal halide fixtures can produce. 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.
