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. We have 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 5 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, we have designed it specifically to be slightly too large to fit.
