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 10W MR11 halogen bulb dimmable?

Yes. Use a compatible 12V transformer and a dimmer that supports the transformer type. Each bulb draws 10W, so check the total connected lamp load against both devices' minimum and maximum load ratings, especially when using one bulb or a small number of bulbs.

Can this GU4 bulb connect directly to 240V mains?

No. It requires a compatible 12V transformer or power supply and a GU4 fitting designed for a 10W MR11 halogen lamp. Check the fitting's wattage rating, space for the 35mm diameter and 38mm length, and required heat clearance before installation.

What features distinguish this DECOSTAR 35S bulb?

This compact MR11 lamp combines a dichroic reflector, glass front cover and UV Stop technology. Its 36° beam provides directional light for accent lighting. This is a halogen lamp, not an LED.
