60W equivalent. More efficient. Save energy and save money. Additionally, QUALILUX Intelligent Energy-Saving Mechanism makes the bulb consume only 50%(3.3W) of the energy while maintaining 70% of the brightness after illuminating for 6 hours that people have gone to bed.
Wide Application

Can these bulbs be used in outdoor fixtures with frosted glass?
QUALILUX Dusk-to-Dawn light sensing bulbs can work perfectly in outdoor fixtures with frosted glass because QUALILUX D2D bulbs can distinguish their own light from other lights based on QUALILUX unique D2D technology. Some Dusk-to-Dawn light bulbs cannot be used in such fixtures because the light reflected by frosted glass will trigger their Dusk-to-Dawn sensor to turn off the light.
Why do they constantly flicker and don’t even try to dim them?
These bulbs are not dimmable. When it is used with a dimmer, it may blink. To use with a dimmer, please select dimmable dusk to dawn light bulbs.
Why does QUALILUX set the power consumption of their Dusk to Dawn light bulbs to be reduced by half after working for 6 hours? No other brand has this function.
People are asleep and require less light after an Outdoor Dusk to Dawn sensor light working for 6 hours. To be more friendly to our planet, QUALILUX set this function on their Dusk to Dawn light bulbs. Even so, the bulbs will keep around 70% brightness after working 6 hours. This still provide good security functions for your house.
