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 JayB GLS incandescent bulb has a frosted glass envelope and a B22 bayonet cap. Rated at 220V / 240V and 40W, it produces 380lm of 2700K warm white light. The frosted glass conceals the filament compared with a clear bulb.

Measuring 60mm in diameter by 105mm overall length, this dimmable bulb has a rated average life of 1,000 hours. Choose a complete fitting approved for its supply and a 40W incandescent load, with suitable heat tolerance, ventilation and clearance. For dimming, check minimum and maximum total connected load, particularly with one 40W bulb.

Frequently Asked Questions

Is the JayB 4621 40W incandescent bulb dimmable?

Yes, this bulb is dimmable. Check the dimmer's minimum and maximum total connected load. A single 40W bulb may be below some dimmers' minimum load, so calculate the combined wattage of all connected bulbs.

This bulb has a B22 bayonet cap and measures 60mm in diameter by 105mm overall length. Match its 220V / 240V rating to the fitting's approved supply, and ensure the complete fitting is rated for a 40W incandescent lamp with adequate heat tolerance, ventilation and clearance. It does not fit E27 or E14 screw holders.

What light does this JayB 40W frosted bulb produce?

It produces 380 lumens of 2700K warm white light. The frosted GLS glass conceals the filament compared with a clear bulb. This is a 40W incandescent bulb, not an LED, with a rated average life of 1,000 hours.
