Specifications & Dimensions
Specifications Beam AngleSpecifications
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.
More information about beam angles.
55 Degrees BrandSpecifications Collingwood Lighting CRISpecifications
CRI stands for Colour Rendering Index. It is a measurement of how well a light source can render the true colour of an object compared to natural light.
Rated out of 100, with an open flame or sunlight being a perfect 100. A light with 90 CRI and above would be classed as having high CRI, while 80 CRI is the standard for LEDs.
80 Ra Cap Type Integrated LED Colour TemperatureSpecifications
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.

Dimensions Located Below Specifications Table Dimmable Yes Double Insulated Yes Downlight TypeSpecifications
Recessed downlights are available in different types such as fixed, adjustable and bathroom (IP65).
Fixed downlights shine the light directly downards. Adjustable downlights allow you to redirect the angle of light onto a specific object or area.
IP65 downlights are water resistant and suitable for use in bathroom zones 1 & 2. Most integrated LED downlights are IP65 rated as standard. This means they can be used anywhere including kitchens and living rooms etc.
Fixed GU10 downlights don't offer any resistance to water, their IP rating is usually IP20. They have no seal and cost less.
Adjustable Finish Fire Rated Yes IP RatingSpecifications
IP (International or Ingress Protection) defines a products level of resistance to dust and moisture. The first digit is for dust and the second digit is for moisture.
Anything higher than IP44 can be used in bathroom zones 1 and 2. IP44 is splash proof and resistance to particles larger than 1mm.
An IP65 rating offers a higher resistance to moisture and is generally used outdoors. IP65 is usually specified for bathroom downlights but according to the Building Regulations, IP44 provides adequate protection.
An IP68 rating is fully water resistant and can be submersed in water, up to 1M in depth.
IP65 Insulation CoverableSpecifications
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.Insulation coverable downlights allow you to place thermal insulation directly on top of them.More information about insulation coverable downlights.
