I'm undertaking a miniature diorama hobby project. I want to mount lights (LED bulbs) on something and, if possible, not use a wired battery setup so that these bulbs can be switched out using neodymium magnets. That is: I want to be able to pluck the bulbs off and pop them back on.So my question is: what is the smallest possible LED bulb available commercially that includes a [detachable] battery within the bulb fitting?- It doesn't require an off/off switch. Inserting/removing the battery is fine.- It doesn't require any particular colour, though it would be nice to have choices.- Realistically, the maximum width I would prefer is about 5-6mm.Anything like this available?For example:Something like this, but smaller (these are 15mm). via /r/DIY https://ift.tt/2uxce9p
