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 Crompton clear incandescent indicator light bulb has a narrow glass body, visible filament and an E12 candelabra screw base. It is for compatible commercial and industrial control panels, switchboards, status indicators, display lighting and amusement equipment.

This E12, 250V, 5/7W clear bulb provides 3000K warm white light. It is for indoor use or protected exterior fittings only. It measures 16mm diameter by 45mm overall length and has a 1,000-hour rated average life. Match the equipment's exact replacement specification and do not assume low-voltage torch or vehicle compatibility merely because the cap fits. The 5/7W rating does not indicate selectable wattage.

Frequently Asked Questions

Is this Crompton E12 indicator bulb dimmable?

Dimming compatibility is not confirmed by the supplied packaging. The previous SEO text said non-dimmable, but that claim is not verified by these images and the specification field is blank. Do not use a dimmer unless the supplier and equipment manufacturer confirm compatibility for this exact lamp and load.

Can I use this E12 bulb in any indicator, torch or vehicle?

No. Match the exact equipment specification for the E12 base, 250V and packaging-marked 5/7W rating, and check the listed 16 x 45mm dimensions. A matching cap does not establish low-voltage torch or automotive suitability. The carton specifies indoor use or protected exterior fittings only; it does not establish a weatherproof lamp. Have a qualified person isolate and service control panels or switchboards.

What does 5/7W mean, and is the colour temperature confirmed?

The carton explicitly prints 5/7W, but does not explain that notation. It should not be interpreted as a selectable two-power lamp or a multipack; confirm the exact required replacement rating with the supplier. The carton does confirm 3000K warm white, replacing the previous 2700K field. The existing 1,000-hour rated life and 16 x 45mm dimensions are retained as listing data, not independently confirmed packaging facts.
