A key switch determines many things, including the depth at which a keystroke is actuated and whether or not there's any associated feedback. The benefit of illuminated keys is debatable, but the overwhelming consensus is that key switches, the mechanism that registers each keystroke, can make or break a gaming keyboard. While colorful lighting effects may add an enticing amount of flash to a headset or mouse, there's potential that a keyboard with individually lit keys might provide an actual advantage during gameplay. Now, Razer's joined the RGB party, updating four existing peripherals with multicolor lighting to its lineup, including the Death Adder mouse, the 7.1 channel Kraken headset, and most notably, the BlackWidow mechanical keyboard. Adjustable, full spectrum RGB lighting has arrived, and as noted in our Corsair Gaming K70 keyboard review, it adds significant character to otherwise standard gear. Hardware manufacturers have been adding lights to gaming peripherals for years, but gone are the days when you have to settle for one color per device.
