Like fluorescent lights, metal halides require a ballast to provide high starting voltages and to regulate current inside the bulb during operation. … This is why a metal halide bulb will not work in a standard household lighting fixture — aside from the fact that the larger E39 base will not fit.
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. … Some MH lamps are self-extinguishing-they will automatically extinguish if the outer envelope is broken.
Do you need a ballast for metal halide lamps?
Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. … Regulating lamp current and power: The ballast regulates the lamp operating current flowing through the lamp after the lamp has been started.
What voltage are metal halide bulbs?
Most metal halide ballasts operate on 120-277V. These are called 4-tap ballasts and they operate 120/208/240/277V.
What happens if you touch a metal halide bulb?
The oils and etc on your hands can get on the bulb. This can cause etching and hot spots on the bulb that can cause issues.
What are energy saver bulbs?
Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact. a Light-emitting diode bulb.
Do CMH bulbs explode?
iPower 315W CMH Bulb 4200K
iPower 315w CDM bulb has a PGZ18 base – open rated for use with open fixtures – meaning they have a secondary protective filament casing and will not explode or catch fire.
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.
Can you put an LED bulb in a metal halide fixture?
Light-emitting diode (LED) technology advancements now allow you to retrofit your metal halide lamps with a simple bulb change. LEDs can give you comparable lumens at a fraction of the energy cost. They are also longer-lived and show a lower reduction of performance over their service life.
When should I change my metal halide bulbs?
In the case of Metal Halide, most manufacturers rate these HID light bulbs with a life of approximately 20,000 hours. This rating traditionally means the point in which 50% of the lamps will fail, but in the case of maintenance, this is the DO NOT EXCEED time of all lamps. At this point, all lamps should be replaced.
