JCC V50 Colour Switchable 3000/4000K LED Downlight Fire Rated

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.

CRI stands for Colour Rendering Index. It is a measurement of how well a light source renders the true colour of an object compared to natural light. 

Rated out of 100, with daylight scoring a perfect 100. A light with 90 CRI and above is classed as being high CRI, while 80 CRI is the standard rating for LED lighting.

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.

The finish or colour of your product is an important decision. If possilbe, try matching your light fittings and switches & sockets with the same finish. Matt white is the most popular downlight finish.

Fire-rated downlights are recessed lighting fixtures designed to maintain the integrity of a ceiling's fire resistance rating by preventing the spread of fire through the openings created for the lights.

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.

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.

Each color temperature has its unique ambiance and use cases. When choosing LED lighting, it's important to consider the mood and functionality you want to achieve in each room or space.

AC standards for alternating current and DC standards for direct current.

Mains voltage is 230V AC and has a tolerance of 10%, some products are 220V or 240V AC which means they can be classed as mains voltage.

DC voltages usually require an LED driver to convert the mains voltage AC into low voltage DC. Popular DC voltages are 12V or 24V DC.
