Avoid panels that only have a two year warranty.Panels under £12 will go yellow, ripple or warp much quicker.

When it comes to LED panels price does indicate quality. Choose a panel that is at least £12 - 30 (or £30 – 50 for higher end).An aluminium plate that protects the components.The better the back cover fits the frame, the better the heat dissipation which means the panel is likely to last longer.Cheap plastic heat sinks don’t work as effectively as metal heat sinks and can reduce the life expectancy of the LEDs in the panel.This helps to prevent LED panels from overheating as a conductive metal heat sink takes away excess heat to keep the panel cool.A poor quality heat sink will mean not enough heat is dissipated from the LED chips which can cause the chips to burnout.Issues with the reflector plate can cause glare.This reflects light back into the light guide plate.

Overtime, plastic diffusers can discolour at the edges and turn yellow, reducing the quality of light produced by the LED panel.

This ensures the light coming from the LEDs is evenly distributed and helps to reduce glare.A low quality diffuser, made from acrylic or PMMA rather than polycarbonate, won’t distribute light as evenly.

This points the light coming from the LEDs towards the diffuser.If it’s not fitted correctly then this can impact on the amount of light and the angle of the light reaching the diffuser.

If low quality LED chips are used in a panel this can produce a ‘blue’ hue which can make a room look cold.

Depending on the type of panel, they are mounted to the back or sides of the panel.Low quality chips can cause a number of problems including the panel becoming dim or the colour quality being compromised.

These chips are mounted to a circuit board and are what produce the light.

Usually made of aluminium, the frame contains the light within the panel.If the frame is too light or is made of a material other than aluminium (cheap LED panels often feature a plastic frame), then this could create excess heat and increase the risk of burn out from overheating.
