No, we do not recommend using our LED light bulbs on a dimmer switch, this type of switch can potentially cause damage to the bulb. Some dimmer switches do not have a true "off" position and may continue to illuminate an LED bulb when turned all the way down because LED bulbs use so little power.

Due to the low power consumption of the LED bulbs they do not work with all of the photo cell light controls found in light fixtures. On some models they will not turn off and with others they may blink. Because of this we do not recommend using them with a light fixture that is activated by a photo cell. It is possible for the bulbs to be damaged from the blinking.

No.

Follow your local disposal procedure for electronic products with circuit boards in them.

No.

The size is E-26. This size works in all common fixtures.

Our night light is a standard ½” candelabra base (similar to an old fashion Christmas tree light).

PAR stands for Parabolic Aluminum Reflector. The number at the end is a unit of bulb measurement. In this system of lamp identification, the first number denotes the maximum diameter of the lamp expressed as increments of 1/8th of an inch.
For example, some common sizes are:

PAR-38 (4.75")
PAR-30 (3.75")
PAR-20 (2.5")

All of our bulbs currently are “medium” or “Edison” base; which means they will fit into most sockets in the US.

Any temperature below 14° F or above 122° F may cause a LED bulb to flicker, dim, change color, or cease to function. Once the LED bulb is returned to an operational environment it may began to work properly, but it also may be permanently damaged. They should not be used in an enclosed fixture with a cover over it. This will raise the temperature.

The 12 Volt Bulbs can operate safely from 9 Volts up to 15 Volts. At 9 Volts the output will be dim.

Their AC voltage tolerance is +/- 10%.

No, but you should never point an LED light into your eyes. The light is very bright and could cause damage.

Some incandescent bulbs do last longer but there are some downsides to them. One way to make incandescent last longer is to increase the thickness of the filament so that it will not deteriorate as quickly. The down side to this is that it takes more energy to heat the filament and the filament does not glow as bright. These types of long-life bulbs typically glow an orange color. If you purchase a long-life incandescent bulb you might find that a 100 watt bulb only puts out the light of a 75 watt bulb while it consumes 100 watts. The amount of money wasted in energy with this type of bulb means you would have been better off purchasing a regular bulb.

Another way to make an incandescent last longer is to use a rare gas called Krypton gas; and no, it does not come from Superman's home planet. Krypton gas is denser than the standard gas used (Argon gas) and helps to keep the filament from deteriorating as fast. You will find that "premium" incandescent light bulbs contain Krypton gas, but unfortunately cost more money.

All of our LED bulbs are for indoor use only except where noted.
