Too few LEDs being used. Too few LEDs (generally 36 or less) means that they have to be driven at a high current to generate the light output needed. Compared with designs using more LEDs, this is less efficient (LEDs perform most efficiently with low drive currents), generates more heat, shortens the life of the LEDs and hastens the lumen depreciation.
Plastic bodies. The better back-lit panels use a metal body. This is more effective as a heat sink than a (cheaper) plastic body. LEDs generate some heat and this needs to be dissipated if their life is not to be shortened further.
Light distribution not overlapping. In a good back-lit panel each LED is individually lensed and the lenses are designed so that the light from each LED overlaps the light from its neighbours. This will produce an even lit affect and some resilience in the event that a single LED fails. Poor lens design and a low number of LEDs is likely to decrease the overlap between LEDs and increase the risk of bright and dark spots on the front of the fitting.
Are the lenses firmly fixed in position? Only time will tell, but the risk is that the heat generated by the LEDs, combined with cheap adhesive poorly applied, will cause the lenses to fall off. The result will be uneven light distribution and possibly glare too.
Built-in driver. Manufacturers can save money by building the driver into the body, but this has multiple drawbacks. It can’t be replaced in case of a problem and there will be no dimming or emergency options. It is a very inflexible approach.
The user can adjust the tension of the free-floating tilt to match their body weight. Max Weight Capacity: 150kg. Fully adjustable height with a 360-degree swivel offers a flexible range of motion. This chair can easily adjust the height of the seats according to human spine structure, providing neck, shoulder, waist, and coccyx protection for long hour sitting. The wide padded seat is covered with breathable densely woven polyester fabric that prevents dirt, dust, and food particles from settling into the fiber of this computer chair.
