Sharp DL18AN LED lightbulb

Finally caught a shot of what you can normally see on the live screen of a smartphone digital camera, but had trouble rendering in the photo. Well, here we are. Among dozens of LED light bulbs on the display racks, I found only the Sharp brand flickered visibly to the cameraphone. This matches my observations at home. In the shop, your eyes normally do not detect the flicker, it is too bright all around. But if the LED bulb is the single source of illumination, and you see stroboscopic effects when moving things, this flickering may tire out your eyes.
