Downlights

A narrow beam angle of 25 degrees will provide a more focused and intense light. Ideal for illuminating specific objects like picture frames on a track lighting system.

A medium beam angle of 40 degrees will provide an even spread of light with a decent intensity. Ideal for smaller rooms like bathrooms.

A wider 60 degree beam can allow you to space downlights further apart, especially when you've got brighter LEDs. Wider downlight distances = fewer downlights which saves money especially in larger rooms like lounges.

Insulation coverable downlights are specially designed fittings that are either fitted with an insulation cover cap or use their own structure as a barrier.

They allow you to lay thermal insulation on top of the downlights. Cutting around thermal insulation isn't energy efficient as the warm air escapes through the downlight holes.

Downlights are available in 3 main types that include:

• Fixed
  Directs the angle of light directly downwards and offers no resistance to water. Usually IP20 rated.
  
  
• Adjustable
  Tilt-able, also known as gimbal downlights, provide you with the ability to adjust the direction of light. Some adjustable downlights are available with IP ratings which allows them to be installed in bathrooms.
  
  
• Bathroom (IP65)
  Water resistant for use in bathroom zones 1 & 2. Most integrated LED downlights are IP65 rated as standard making them a more universal option. With a fixed postion, they're not just limited to bathroom use.

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.

An IP65 rating offers a high resistance to moisture and is popular rating for outdoor lighting and electrical enclosures.

IP65 is usually specified for bathroom downlights but according to the Building Regulations, IP44 provides adequate protection for zones 1 & 2.
