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.

This GE Krypton mushroom incandescent light bulb has an opal glass finish, a broad rounded crown and an E27 Edison screw cap. Its distinctive mushroom profile offers an alternative to a standard pear-shaped bulb in compatible lamps and decorative fittings.

This GE Krypton opal lamp is rated 240V and 100W with an E27 cap. It provides 1,720lm output, 2800K warm white light, dimmable operation and a 1,000-hour rated average life, with dimensions of 55mm diameter by 90mm length. Check the fitting's maximum incandescent wattage, enclosure requirements and heat clearance: its compact dimensions do not make a 100W lamp suitable for a lower-rated fitting. The mushroom shape alone does not establish a directional reflector beam or compatibility with downlights.

Frequently Asked Questions

Can this GE Krypton 100W mushroom bulb be dimmed?

The existing specifications identify it as dimmable. Use a control suitable for incandescent lamps and check its minimum and maximum connected load, including all lamps on the control. Each bulb draws a full 100W, not an LED-equivalent wattage. Compatibility with every dimmer or LED-only control is not guaranteed.

Will this compact mushroom bulb fit my lamp or downlight?

Check for an E27 socket, compatibility with a 240V 100W incandescent lamp and clearance for the listed 55 x 90mm dimensions. Follow the fitting's maximum wattage, enclosure and heat-clearance instructions. A compact lamp is not automatically safe in a small downlight or a fitting rated below 100W, and the mushroom shape does not establish downlight compatibility. Switch off power and let the bulb cool before replacement.

Is this an R63 reflector or an energy-saving LED?

This is a GE Krypton 100W incandescent bulb with mushroom-shaped opal glass, not an LED. The supplied packaging confirms Krypton, Opal, 240V and E27, but does not identify an R63 size or a reflector beam angle. No energy-saving comparison or guaranteed glare-free performance is established. The existing 1,720lm and 2800K values are retained as listing specifications, not independently verified packaging facts.
