4w GU10 LED Spotlight, 36 Degree beam angle, Warm White 2700k, 360 Lumens, Non Dimmable

One of our very best sellers is this 4w GU10 LED bulb. It has a 36 degree medium beam in a warm white colour temperature 2700k and gives 360 lumen brightness.
  It is non dimmable,  Mains 240v and a direct replacement for the inefficient halogen GU10 bulbs.

The key benefits are that the LED bulbs give low energy consumption, have a long lifetime of up to 15,000 hours, and far better than the Halogen GU10 35w and 50w bulbs.  They have effective heat distribution which means they are very cool to touch and come with a 2 year warranty.

They can be used for a variety of applications including domestic applications, retail, shopfronts, exhibitions and display cabinets too.

The bulb is 50mm in diameter and 54mm in length.

Example of LED lamp energy savings

Lamp colour ( Kelvins )

The colour of a lamp is defined as a measurement called kelvins. A standard GLS light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum and a lamp with 5,000 kelvins would be at the very cold white spectrum. Getting the right colour temperature of a lamp does matter as the warm colour wavelength helps to soften the tone of the area and gives a warm soft relaxed feel and ideal for colourful flower beds and rockery areas especially with wooden bark and at the other end of the scale a 4,000 to 5,000 kelvin lamp colour would be used against a light background such as white walls or to accentuate grey blueish foliage in shrubs and small trees.  When you buy a new, energy efficient bulb, keep your application and colour scheme in mind and make sure to buy the bulb with a colour temperature to match. Coloured filters are good to use with the LED bulbs too especially in winter using green filters give the appearance the trees are still in leaf.


Light output ( Lumens )

The amount of light that is produced by a lamp is called lumens and the more lumens the lamp has the brighter it will be. Lumens work in conjunction with kelvins and should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp which was a cool white 5,000 kelvins which also produced 300 lumens the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 5,000 kelvin light onto a dark wall and a warm 2,700 kelvin lamp onto a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take into account the area you want to illuminate and think about Kelvins ( colour ),  Lumens ( brightness) and contrast   ( colour of area).
