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 OSRAM blue 40W incandescent bulb be dimmed?

The existing specification identifies it as dimmable, although the supplied packaging views do not independently confirm that rating. Use a dimmer approved for incandescent lamps and check minimum and maximum load across all connected bulbs. Do not assume compatibility with LED-only dimmers or every smart switch.

Will this blue GLS bulb fit my decorative light or outdoor display?

Match the packaging-marked B22d bayonet cap, 240V and 40W to the fitting requirements. Check the listed 60mm diameter and 105mm length, maximum incandescent wattage, clearance and ventilation. A matching cap alone does not establish suitability. No weatherproof rating is confirmed, so do not use it exposed to rain or assume suitability for an outdoor string-light system. Switch off power and let the lamp cool before replacement.

Is this a blue bulb or a 2700K warm white bulb, and where is it made?

The packaging explicitly identifies the lamp as Blue. The previous 2700K white-light colour-temperature value has been removed rather than used to describe its coloured output. The carton states manufacture by OSRAM Slovakia, conflicting with the saved China origin; actual stock or batch should be checked before changing that record. Internal coating composition, cadmium-free status, fusing and the previous certification claim are not verified by the supplied images.
