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 Crompton R80 40W reflector bulb be dimmed?

The existing specification lists this lamp as dimmable, although the supplied carton view does not independently confirm that rating. Use a dimmer approved for incandescent lamps and check its minimum and maximum load with all connected lamps included. Do not assume compatibility with LED-only controls or every smart switch.

Will this R80 B22 bulb fit my spotlight or display fitting?

Match the R80 reflector shape, B22 bayonet cap, 240V and 40W rating to the fitting's requirements. Check the listed 80mm diameter and 110mm length, shade clearance, ventilation and maximum incandescent wattage. A matching cap alone does not establish suitability for a recessed or enclosed fitting. Switch off power and allow the lamp to cool before replacement.

What distinguishes this R80 reflector from a standard GLS bulb?

This lamp has a broad reflector-style body and satin-finish front face rather than the rounded all-clear profile of a standard GLS bulb. The carton identifies R80, B22, 240V and 40W. No beam angle, lumen output or glare-reduction performance is confirmed, and the supplied images do not verify the previous internal-fuse or certification claims. The listed 2700K and 1,000-hour figures are retained from existing specifications.
