The LED lamp is really bright, but after a while you get used to it. The 1400 lumen definitely help accurately distinguish different colors (for example to find matching black socks) that look all at a 'yellow' light much the same. The light in my opinion is by no means uncomfortable, especially in the morning you will be so fast-growing: D The walls seem very bright and very white. The bulb is not particularly hot, they can always touch (both as amended and on the piston). Compared with the slightly smaller warm-white version of the Philips lamp remains significantly cooler. With a beam angle of 220 ° also comes to enough light on the ceiling.
