Miniature Surface or Recessed Downlight 3 Set Malmbergs MD-29

Every light source from an LED to a simple wax candle has a beam angle. A beam angle is a measurement of how the light is distributed. GU10 LEDs and recessed downlights have a fairly narrow beam of around 40 degrees, anything within 5 degrees is classed as a medium beam.

A wax candle or traditional light bulb would have a beam angle of 360 degrees as the light shines all the way around but is less intense.

Combing brighter downlights with wider 60 degree beams allows you to space them out further, reducing the total amount of lights needed.

Colour temperature is a measurement of appearance. Measured in Kelvins, the lower the rating, the warmer the light appears. Choosing the right temperature can have a dramatic effect on a room.

2700K - Extra Warm White

Similar to a traditional incandescent light bulb or halogen. It has a more orange and warmer tone, with a ‘soft white’ appearance. Ideal for living rooms.

3000K - Warm White

Clearer, but still quite warm. This is the ‘new norm’ for general lighting and is the most popular option. If you’re unsure I’d recommend trying this one.

4000K - Cool White

Clearer, whiter and crisp; used in commercial locations including supermarkets. Cool white appears brighter than warm white as the LED is covered in less phosphor. It can make a room appear cold and clinical but used correctly (white walls etc) it can make a room appear cleaner and modern.

In order to achieve Part L Compliance (energy efficiency) you shouldn't cut around thermal insulation. If you do this your home or building won't be energy efficient as valuable heat will escape through the hole of the downlight.

A downlight can act like a chimney and draw out warm, rising air from a room, up into the cold space above. The effect is increased in upper floors containing lofts.
