Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

Equivalent Wattages Between Different Light Bulbs

As long as the technology developed, a LED light bulb can only use 8 watt power but light up similar brightness when a incandescent light bulb uses 60 watt power. There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

Frequently Asked Questions

Can this projector lamp be dimmed?

Yes. Use controls approved for the equipment, a compatible halogen dimmer and a dimmable 12V supply. Each lamp draws 100W; keep the load within the supply and control ratings and follow the equipment manufacturer's instructions.

Can this lamp replace any MR11 or medical equipment lamp?

No. Match the equipment manufacturer's specified replacement lamp, including its G5.3 base, 12V 100W rating, 26mm focal length, 35mm diameter, 35mm length and p90/p15 operating position. Medical, dental and laboratory equipment requires the exact approved lamp, not a replacement selected by base alone.
