How does the light output compare to a standard bulb?

The HP36 puts out 210 lumens, which is slightly more than a typical 921 incandescent bulb. The LED light is a brighter, crisper white than the yellowish glow of an incandescent, so it's more noticeable.

Will this bulb flicker or fail prematurely?

No. This bulb uses constant-current circuitry and transient suppression to prevent flickering and extend its lifespan. Diode Dynamics is known for reliable LED products, and this bulb is backed by a three-year replacement warranty.

Is any special equipment needed for installation?

No, this is a simple plug-and-play replacement. Just remove your old bulb and plug in the HP36. The nonpolar design means it will work no matter which way you plug it in.
