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

Is this T29 B15 25W tubular bulb dimmable?

The existing specifications identify this bulb as dimmable. Use a dimmer compatible with incandescent lamps and check its voltage requirements and minimum and maximum connected load, especially when controlling a single 25W bulb. Compatibility is not guaranteed with every dimmer or LED-only control.

Will this tubular bulb fit my picture light or display fitting?

Only if the fitting requires a B15 small bayonet bulb, accepts the listed 29mm diameter and 90mm length, and is suitable for the lamp's 250V, 25W rating. Check the original cap, contacts and locating-pin arrangement as well as physical clearance. B15 is not interchangeable with B22 or a screw cap. The fitting must permit a 25W incandescent lamp. Switch off power and let the bulb cool before replacement.

What distinguishes this T29 clear tubular bulb?

It has an elongated clear glass envelope with a visible filament rather than a candle or rounded GLS shape. T29 corresponds to the listed 29mm tube diameter, while its overall length is listed as 90mm. It is a 25W incandescent lamp, not an LED. Existing specifications state a 1,000-hour rated average life; lumen output and an exact beam angle have not been confirmed.
