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

Is this GE 30W opal strip bulb dimmable?

Dimming compatibility is not confirmed by the existing specifications or supplied packaging. Check the lamp supplier's and fitting manufacturer's instructions for this exact lamp before using a dimmer. Do not assume compatibility with every household dimmer or LED-only control.

Will this 284mm lamp fit my picture light or display cabinet?

Match the original lamp's exact end caps and holder arrangement, overall length, diameter and electrical rating to the fitting requirements. The packaging confirms 30W and 284mm; existing specifications list S15, 240V and 25mm diameter. Check the fitting's maximum incandescent wattage, ventilation and heat clearance. Different strip-lamp lengths are not interchangeable merely because they look similar. Switch off power and let the lamp cool before replacement.

How does the opal version differ from a clear strip lamp or an LED?

This is a traditional 30W incandescent strip lamp, not an LED strip or fluorescent tube. The opal glass conceals the internal filament more than a clear tube, but does not guarantee glare-free or perfectly even lighting in every fitting. The packaging confirms GE, Opal, 30W and 284mm. The existing 2700K, 200lm and 1,000-hour figures are retained as listing specifications, not independently verified packaging facts.
