2013 Shanghai LED Lighting supply E27 LED spotlights, GU10 LED spot light bulbs. LED 5W bulb and GU10 Light Bulb Manufacturers China. Most white light LED GU10 bulbs emit a light colour ranging from "warm white" to "cool white". Warm white is slightly yellow similar to light emitted by a halogen or filament bulb. Cool white has a slight blue tint and is rarely used for domestic lighting purposes. In-between these two we have Pure white. Pure white is just that - a clean white light with no yellow or blue tint. The Kelvin scale is used as a measure of light colour, warm white ranges from about 2800k to 3800k, pure white or daylight from about 4800k to 6000k, and cool white starts from around 6000k upwards.

Can you tell the difference? Well, yes you almost certainly can but which is which, and more to the point which do you prefer?

In the photograph you see a bathroom lit by 3 x 50W halogen GU10 lamps and the right hand side is the exact same space lit by 3 x 6W warm white LED GU10 bulbs Shanghai LED Lighting, in other words 150 watts versus 18. With 6 watts total these Edison GU10 LED bulbs were among the most powerful mains voltage LED spots currently on the domestic market and a perfectly valid replacement for 50W GU10 halogen spots.

One thing to note though is that whereas most 3 x 1W LED spots are at best a match for a regular 35W lamp, doubling the power does not double the amount of light. LED lighting does not scale in a linear fashion where power is concerned so a 6W LED lamp is probably no more than 50% brighter at best than a 3W one - not twice as bright, as you might quite reasonably have imagined. But brighter is nonetheless brighter and these Shanghai LED Lighting 6W Edison LEDs are definitely bright enough to replace 50W halogens.

It's worth checking the dimensions of the LED bulb to ensure it will fit inside the original bulb housing or light fitting. If fitted in the ceiling check the height of the ceiling void is adequate for the length of the bulb. While the diameter of the bulb face is always 50mm for Shanghai LED Lighting GU10 and MR16 bulbs the length and width of the bulb body varies. On our website we provide technical drawings of all our LED GU10 and MR16 bulbs. If however you purchase an LED bulb and find it's not suitable, simply return it to us for a refund - see our returns policy.
