Bugs aren"t as attracted to this yellow CFL flood light bulb as they are to regular white bulbs, making this a perfect choice for patio or garage areas. Same light output as a 100 watt bulb, but uses only 23 watts of energy. Weather proof, but is not dimmable. PAR38. 23 watt. 8,000 hour average life. Price is for one CFL bulb. One CFL bulb per pack.
