HID Lamps & Bulbs

When it comes to lighting large, industrial areas, it's important to have the most intense and efficient lighting possible. HID (High Intensity Discharge) lamps and bulbs are designed to deliver a superior brightness when compared to other bulbs. Here at Cromwell, we have a wide range of HID Lamps & Bulbs from leading brands such as Venture Lighting, GE Lighting and Philips.

Why HID lamps and bulbs?

HID (High Intensity Discharge) lamps and bulbs are effective at delivering the most amount of light per watt possible. Because of this, they are primarily used in places where maximum lighting is critical. Common applications of HID lamps and bulbs are streetlights, floodlights, construction sites, vehicle headlights, sporting stadiums and gymnasiums as well as plant growing rooms or industrial greenhouses.

HID lamp and bulb types

Whilst there are many sizes and types of bulbs and fittings, we've outlined the most common types that are found on HID lamps and bulbs below to ensure you find the right product for your needs.

• E40   -   The E refers to the Edison Screw type fitting of the bulb, whilst the 40 refers to the diameter of the holder that the bub is designed to fit into, in mm. This is one of the largest diameter fittings of common bulbs.

• E27   -   As with the E40 bulb, an E27 bulb possesses an Edison Screw fitting type, but is suited for use with 27mm diameter bulb holders.

• RX7S   -   This type of fitting if found commonly on the end of double ended metal halide bulbs and lamps. They are most commonly found in the retail and hospitality sectors.

• G12   -   Bulbs that have G12 base types possess two pins that are 12mm apart from each other. It uses a ceramic base as the contact point.

• G8.5   -   As above, the G8.5 bulb type possesses two pins using a ceramic base as a contact point. However, the pins are spaced 8.5mm apart on the G8.5 spec.

• FC2   -   Similarly to RX7S fittings, the FC2 fitting is primarily found on double ended metal halide bulbs and lamps.

FAQs

Which is better, LED or HID?

This largely depends upon your intended application. LED lightbulbs and lamps have a longer lifespan of approximately 100,000 hours and are slightly more energy efficient. They use electricity to produce light, whereas HID bulbs and lamps use gas and metals to heat a filament and produce light and can last up to around 25,000 hours. However, HID lights produce a higher intensity light and are therefore commonly used where intense lighting is required.
