Types of 250 Watt Metal Halide Bulb

A 250-watt metal halide bulb is a type of high-intensity discharge (HID) light. It is commonly used for outdoor and industrial lighting applications. This includes sports facilities, parking lots, streetlights, and commercial warehouses. The bulb consists of a glass tube filled with gas and metal salts. It has a filament and ballast, which are necessary components for the light to function.

The bulb produces a bright, white light that is similar to natural daylight. It has a color temperature of around 4,000 to 5,000 Kelvin. The light is suitable for illuminating large areas. It is available in different types and designs depending on the use and the industry standards. The most common types are as follows:

• Coated and Uncoated Bulb:

  The 250-watt metal halide bulb comes in coated and uncoated variants. The coated bulbs have a phosphor coating inside the glass. This coating helps to diffuse light and reduce glare. On the other hand, the uncoated bulbs do not have this coating. As a result, they produce a harsher light with more glare. The coated bulbs are better for areas where glare needs to be minimized. This includes retail spaces and hospitals. The uncoated bulbs are better for general illumination where glare is not a problem.

• Clear and Elliptical Bulb:

  The clear bulb has a transparent glass envelope. This design allows the light to shine without any obstruction. On the other hand, the elliptical bulb has a special shaped glass envelope. This design focuses and directs the light more efficiently. The clear bulb is mostly used in areas where a high level of brightness is needed. The elliptical bulb is a good choice for places where light needs to be directed. This includes track lighting and display cases.

• Mogul Base Metal Halide Bulb:

  The 250-watt metal halide bulbs can also be fitted with a mogul base. This is a larger base type compared to the standard medium base. The mogul base is better at handling the heat and pressure inside the bulb. It also provides a more stable electrical connection. The mogul base bulbs are used in high-intensity applications like gymnasiums and stadiums.
