Vlak makes high-tech lighting. For the new vlak 2, lithium batteries are reclaimed from discarded laptops, electric bikes and electric cars. The lamp is fitted with three of these batteries, allowing it to run for 5 hours at full brightness or 30 hours at reduced brightness. Twist the knob and a soothing, warm light appears. Turn further, and the light becomes a bright day-light shine, just like the old-fashioned light bulb.
