Hello, I am designing a product for a large essential oil company - their customers have 15ml amber bottles left over and we want to create a single bulb top that could screw onto the bottle and then be hung from the tree like an ornament. Tea lights LEDs might be strong enough, but they might last 150 hours. I'm hoping to find something that could last through the holiday season. Any suggestions on LED/battery combo? Is it even possible given the small size? TIA!
