It's a pretty nifty desk lamp that mounts onto your monitor - but is it worth £89? The BenQ ScreenBar claims to prevent eyestrain if you’re staring at your monitor for long periods of time, while it also saves desk space since it mounts to the top of your monitor. This above monitor mounting and rotatable design also prevents glare as the lamp doesn’t shine directly on your screen, while the ambient light sensor enables the ScreenBar to automatically adjust its brightness to your surroundings.

The list of features looks really promising, but for £89, does this blow all other desk lights out of the water, or is it simply over-engineered?
