That's a good question. And one we hear from time to time.
It's 99% odds that the culprit is your set of batteries. As the battery lights drain the batteries, bulbs randomly start to dim. They don't go out all at once. This is true of the incandescent and the LED sets. In fact, on the LED sets that are multi color, the blue and green bulbs go dimmer before the rest of the bulbs.
It's hard to know when you purchase a set of batteries how long they've been on the shelf. For your special event, we suggest that you purchase brand-name batteries from a store that has good turnover.
Keep in mind the following operation estimates per battery set on our different battery light families:
- Standard Incandescent Battery Lights: 4-7 hours (requires 2 C batteries not included)
- LED Battery Lights: 18-24 hours (requires 3 AA batteries not included)
- LED Fairy Lights (microdrop): 100-150 hours (requires 3 AA batteries not included)
Be sure to test your battery lights when you receive them to make sure there are no manufacturing issues - which can pop up from time to time. Let us know if you have an issue via our contact page so we can send you a replacement set.<.p>
Also, consider waiting until the last minute until you turn on your battery lights. We've had some customers ask their guests to turn on their centerpieces all at one for a lovely affect.
