What is HQI metal halide?

Metal Halide bulbs (HQI) are one of the best alternatives to natural light. MEGACHROME metal halide lamps are characterized by a long lifetime and highest color stability. …

What is the difference between metal halide and pulse start metal halide?

Traditional metal halide (MH) lamps use probe-start technology. Pulse-start MH lamps do not have the starting probe electrode (Figure 2). Instead they have a high-voltage ignitor that works with the ballast to start the lamp using a series of high-voltage pulses (typically 3 to 5 kilovolts).

What is a Hqi light?

HQI stands for hydrargyrum quartz iodide. Like HMI, HQI lamps are a subset (or type) of metal halide lamps, which in turn are a subset of high-intensity discharge (HID) lamps. They should not be confused with quartz halogen lamps, which are a specialized type of incandescent lamp.

Can I replace metal halide with high pressure sodium?

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs.

What is the difference between MH and HPS?

Metal Halide (MH) lamps provide more of the blue spectrum, which is ideal for leafy crops, and/or plants that are in a vegetative stage. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.

Can I put a metal halide bulb in a regular socket?

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.

What kind of halide lamp is used for photography?

The HMI. Another kind of metal halide lamp is the halogen metal iodide or HMI lamp. It is mainly used for photography since it makes a 5600 K light (matching natural daylight) and has a great CRI. The lamp has a optimum combination of metal halides made of rare earth metals.

Why are metal halide lights better than LEDs?

Another disadvantage to LEDs when compared to MH lamps is their ability to produce white light. Metal halide lamps are great because of their vivid white “natural” light that they emit. With LEDs, there really is no such thing as “white light”. You have to use a number of different colors to eventually get white light.

Is there such thing as a white halide light?

Metal halide lamps are great because of their vivid white “natural” light that they emit. With LEDs, there really is no such thing as “white light”. You have to use a number of different colors to eventually get white light. This means sometimes the light can be too blue.

What can I use to replace a metal halide lamp?

To replace one MH lamp usually requires multiple fluorescent lamps to produce the same amount of light. This 120 watt corn lamp can replace a 400 watt metal halide lamp. As the newest kid on the lighting solutions block, there has been much excitement regarding LED lighting.
