What does bt37 mean?

These lamps come in 250, 400, 750 & 1000 Watts. “BT” stands for blown tubular and you will notice these type metal halide bulbs have a small extended round tip on the top to support the metal tabs inside the lamp. The other type is an “ED” which stands for elliptical dimpled.

Do MH bulbs need a ballast?

Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. The ballast is set to deliver relatively stable power to the lamp while regulating the lamp current despite typical line voltage fluctuations.

What is a MH light bulb?

A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp.

What is the difference between E17 and ED17 bulbs?

E17 is the base size (intermediate), a little smaller than the standard E26. ED17 is the shape of the bulb. This bulb is a medium base (E26).

Does Pulse Start lamp work standard ballast?

Some probe start lamps do not have a problem operating on pulse start ballasts. The problem is probe start lamps are not designed for use with a ballast with a high voltage ignitor (lamp starter). They are not designed to handle the high voltage produced by a 2500 volt or more ignitor.

Is metal arc the same as metal halide?

Compared to standard metal halide lamps, METALARC PULSE START lamps reach 90 percent of full light output 30 percent faster and have a 60 percent shorter hot restrike time. METALARC PULSE START lamps may be combined with SYLVANIA HID ballasts to form a complete system.

Do metal halide bulbs explode?

Metal halide (MH) lamps can explode (typically referred to as sudden nonpassive failure) because they operate at high pressures, but some products are manufactured with safety features to prevent injury.

How many lumens is a 1000w metal halide?

So, a 1000 watt metal halide bulb can produce 50,000 lumens to 100,000 lumens. Similarly, a 400 watt bulb of metal halide produces almost 24,000 lumens to 44,000 lumens.

How many lumens is 100w metal halide?

8,500

Is there a difference in metal halide bulbs?

Metal halide lights are 3-5 times as efficient as incandescent bulbs and produce a much higher quality light. In many cases, and depending on the particular mix of metal halides, they have a very high color temperature (up to 5500K).
