Keep annoying bugs and insects away with this color-changing bug light bulb from Feit Electric. In months when bugs aren’t a concern, you can use the bulb as a normal light bulb. When bug season arrives, transform your space into a bug-free zone safely and harmlessly. Use a standard light switch to go between a yellow light that most flying insects cannot see, or a regular 5000K Daylight color temperature light. This bug light provides up to 800 lumens of light while using less energy than an equivalent 60-watt incandescent. Each bulb is rated to last 15,000 hours/13 years, is RoHS compliant, and is 100% mercury free.
