Philips Ultinon Pro3021 H4 Long-life LED bulbs

The best LED light bulbs are designed to last for as long as possible. Philips Ultinon Pro3021 fluorescent lamps have a robust design with a highly efficient heat sink that dissipates heat away from the important components of the lamp.

LED lamps have a lamp life of 2000 hours or 4 times longer than replaceable halogen lamps.

Philips Ultinon Pro3021 H4 Installation

The optimal LED bulb size is crucial for success, as in some spotlights there is only a small amount of space for the bulb. Other LED bulbs on the market have an external control box, but the Philips Ultinon Pro3021 LED bulb has a built-in control box which makes installation quick and easy. The bulb’s compact design allows it to be installed in a wide range of vehicles with the help of a technician.

Philips Ultinon Pro3021 H4 Visibility

While some LED bulbs from other manufacturers are of poor quality, as their brightness and luminous flux do not match the advertised specification, the Philips Ultinon Pro3021 offers optimum efficiency and light quality.

The even beam ensures better visibility without dazzling oncoming motorists, and the high luminance ensures that any obstacles on the road can be seen in good time. For optimum beam alignment it is important that the bulb is fitted correctly in the headlamp housing, therefore always adjust the headlamps after bulb replacement.
