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 T29 B15 25W bulb be dimmed?

The existing specifications identify this bulb as dimmable. Use a dimmer suitable for incandescent lamps and check its minimum and maximum connected load. A single 25W bulb may fall below some dimmers' minimum load, so check the control requirements and total lamp wattage. Compatibility with every dimmer or LED-only control is not guaranteed.

Will this T29 B15 bulb fit my cabinet light or sewing machine?

Use it only where the equipment specifies a compatible B15 small bayonet 25W incandescent lamp and suitable voltage rating. Check the listed 29mm diameter and 100mm overall length, mounting clearance, ventilation and maximum wattage. The carton is marked 240/250V. It is not universally compatible with cabinet lights or sewing machines and does not fit E14/E27 screw or B22 bayonet sockets. Switch off power and let the lamp cool before replacement.

What is confirmed by the packaging, and is this a focused reflector bulb?

The carton identifies Clear Tubular T29, 25W, SBC and 240/250V. This is a clear incandescent tubular bulb, not an LED or a confirmed directional reflector lamp. The supplied photos do not independently confirm the previous AS2325 standard or internal-fuse claims, so those claims have been omitted. The existing 2700K, 1,000-hour life and 29 x 100mm dimensions are retained as listing specifications.
