What does "constant-current circuitry" mean?

Constant-current circuitry regulates the current flowing through the LED. This helps prevent flickering and ensures consistent brightness over the bulb's lifespan. It also protects the LED from voltage spikes that can cause premature failure.

How much brighter is this compared to a stock bulb?

The HP5 puts out 92 lumens, about triple the light of a standard 5W 194 or 168 bulb. If that's too much, Diode Dynamics makes the HP3, which is less bright. Consider the HP3 if you only need a small increase in brightness.

What is the color temperature of this bulb?

This particular bulb is "warm white," or 3000K. If you want a modern, cool white look, consider the 6000K option. Diode Dynamics also offers 5000K (pure white) and 4000K (natural white) options.
