Engineered as a direct replacement for the S8 "pear-shaped" filament bulbs commonly used in interior dome/map lights, convenience lights, storage compartments, etc. Draws only 85 milliamps (versus 1.0amp) for the incandescent models.  We incorporated a diffuser lens cover over the LED to eliminate any "hotspots" in the light projection for a smooth omni-directional illumination. This item is NOT recommended as a signaling light; intended for flood lighting applications.
 
Note regarding voltage selection:
Order 28-volt version if application incorporates a dimmer control (other than PWM dimmer). The brightness of this bulb changes as a function of the voltage (lower voltage=lower brightness; increase voltage = higher brightness). *Supply voltage over 28-volts may affect lifespan of led.
Order 10-30VDC version (25% brighter) if dimming NOT required; OR for dimmable applications, a PWM dimmer control is required. 10-30VDC models maintains constant brightness at any voltage between 10 and 30 volts, which eliminates fluctuations in light output with voltage changes. Also this model internally regulates voltage/current, which eliminates issues with early failures due to poorly regulated voltage supplys. This model also allows installers the ability to keep a single model for use in either 12-volt or 28-volt installations, thus reducing inventory stores.
