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

Rated out of 100, with daylight scoring a perfect 100. Lights with 90 CRI and above are classed as being high CRI. Lights with 80 CRI are the industry standard.

LED lighting color temperatures range from extra warm white (2700K), creating a cozy atmosphere, to daylight white (5000K-6500K), offering a bright, alert setting.

Choosing the right finish or color for your downlights is crucial in achieving a harmonious interior design. For a cohesive aesthetic, consider coordinating the finish of your light fittings with that of your switches and sockets. Matt white remains the top choice for downlight finishes due to its universal appeal and it blends in with white ceilings.

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.

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.

This is the resistance to dust and moisture. The first digit is for the resistance to dust and the second digit is for moisture.

Anything higher than IP44 can be used in bathroom zones 1 and 2.

An IP65 rating offers a higher resistance and is generally used outdoors. 

An IP68 is fully water resistant and can be submersed in water, up to 1M in depth.
