This stand alone light bulb does not need to be attached to a lamp! Looks and feels identical to the iconic filament light bulb, but does not require plugging in. Power-cord free, rechargeable and portable. Timeless and beautiful homage to the humble light bulb. Suck UK has used over 100 tiny LEDs to recreate the look and feel of a traditional incandescent filament from the classic Edison light bulb. Powered by an internal battery with a 4 hour life on a 1.5 hour charge. If Edison could see this, he would be turning in his grave. A small note on safety - this light bulb cannot (even accidentally) be screwed into a mains light fitting, they have designed it specifically to be slightly too large to fit. No heat. No electric shocks. It can be a night light, table decoration, flashlight, or just a cool thing!
