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 ST64 vintage filament bulb combines an amber-tinted teardrop glass envelope with visible decorative filaments and an E27 Edison screw cap. Its classic elongated profile offers a vintage appearance in compatible exposed-bulb pendants and decorative lamps.

This bulb features 240V 25W incandescent operation, dimmability, a 360° beam angle, a 3,000-hour rated average life and dimensions of 64mm diameter by 145mm length. Check the fitting's clearance, maximum incandescent wattage and dimmer requirements; pendant holders are not universally compatible.

Frequently Asked Questions

Is this ST64 25W filament bulb dimmable?

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 not meet every dimmer's minimum load. Compatibility is not guaranteed with LED-only controls or every dimmer. The 25W rating is its actual incandescent electrical load, not an LED-equivalent rating.

Will this ST64 bulb fit my pendant or table lamp?

Check that your fitting requires an E27 screw cap, supports a 240V 25W incandescent lamp and has clearance for the listed 64mm diameter and 145mm overall length. Follow the fitting's shade, enclosure and heat-clearance requirements. An E27 socket alone does not establish compatibility. Switch off power and allow the bulb to cool before replacement.

Is this ST64 bulb an LED, and what is its colour temperature?

It is listed as a traditional 25W incandescent filament bulb, not an LED. The amber-tinted glass, visible filaments and teardrop shape give it its vintage decorative appearance. Previous records state both 2200K and 2300K, so no exact colour temperature is specified pending confirmation. Lumen output has not been confirmed; do not assume a particular task-lighting brightness.
