Low Voltage LED Spike Lights Collingwood SL220

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.

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.

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.

Selecting the appropriate color or finish for your lights and switches is key to creating a unified and attractive interior. Aim to match the finish of your downlights with other elements like switches and sockets. The matt white finish is especially popular for downlights as it seamlessly merges with white ceilings.

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.

Some LED light fittings require an additional LED driver. This can be identified when the input type is anything other than Mains Voltage 230V AC.

Small LED light fittings usually operate on lower voltages as they're safer to run and you can use one LED driver to power multiple lights.

If the input type is 12V or 24V DC, a constant voltage LED driver is required. These are wired in parallel.

If the input type is 350mA or 700mA, a constant current LED driver is required. These are wired in series. It can be easier to wire LED ground lights in series as the power flows in one direction and doesn't need to loop back around.
