The regret comes later.ĭirect lit LED flat panel light will look similar to an edge lit flat panel light when mounted. It’s this process that has made the LED panel market torturously competitive. Despite some fixtures coming without guarantees of build quality or performance, buyers are still very keen to purchase. The unscrupulous panel manufacturer simply buys reels of cheap LED strip, mounts the strip into the frame and fits the diffuser.
Cheap lighting fixtures are cheap for a reason. The guidance on buying any type of LED luminaire stands: a lighting supplier with a decent reputation to maintain will be able to provide full, certified, photometric performance data of its fixtures. We are all aware of ridiculously low prices on LED panel lights available on the internet. At the same time, the unit cost of panel lights is going the other way, with some panel lights being offered at embarrassingly low prices. On the one hand, the lumen output of the LED panel lights is driving ever higher. There are two trends are being watched carefully. It allows them to be mounted on a variety of surfaces, such as underneath cabinets or on concrete ceilings. The advantage of the edge lit LED flat panel lights is undoubtedly their thin size. It’s an inefficient way to get light out of a fixture, but it’s a very cost-effective fixture to manufacture and transport. The light is produced from the sides of the panel and passes through the light guide panel(LGP), then refracted downwards into space. What’s the difference between the edge-lit and backlit panel lights? And what are the advantages and disadvantages of them? Let’s take a look here.
