Osram HCI-TC Powerball gas discharge lamps are extremely efficient bright light sources. With the usage of 400w, these light sources can emit up to 40,000 lumen! But we have several wattages available, so you can pick the amount you desire. The Color Rendering Index of these Osram gas discharge lamps can be very high, which means that colors will be shown very natural. Check the specifications per product to see the CRI. Osram HCI-TC light sources are mostly used in sports stadiums. Always check the base of your lamp before ordering a new one. Osram HCI-TC Powerball lamps have a G8.5 base.
Colour temperature (Kelvin)
The colour temperature refers to the colour produced by a light. It's measured in Kelvin (K) and ranges from warm white (1700K - 3000K) to daylight white (6500K). Neutral white (3100K - 5000K) is mainly used for general lighting applications.

Cap / Base
The cap/base of a bulb is the part that connects it to the socket in the fixture. In the UK, B22 (Bayonet) caps/bases are still the most popular, although E27 (Edison screw) caps/bases are becoming increasingly popular. GU10 is the most common cap/base for spotlights. Check which cap/base you need carefully as many other types are also available.
The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.
