Providing a fully road-legal means of achieving pure white light in a halogen-based package, DiamondVision utilises Philips' patented coating technology to deliver an LED like colour temperature. This combination of the best attributes of LED-based technology in a halogen-based package makes DiamondVision the ideal choice for drivers looking for the crispest, cleanest white light for their vehicle.

The stems and bulbs in Philips halogen and incandescent globes are constructed from quartz, which is stronger and more stable than conventional glass. Quartz is superior to glass in many ways, not least of which due to its uniformly symmetrical molecular structure. The unique properties of quartz verses glass endow Philips globes with substantially higher resistance to the extremely high temperatures experienced by the burning tungsten filament, which can reach temperatures of up to 2650-degrees Celsius. This increased temperature resistance is critical to the service life of the globe as the stem and even the bulb itself can reach temperatures of up to 800-degrees Celsius.

Quartz also offers substantially increased resistance to thermal shock, resulting from high humidity or direct contact of water droplets with the surface of the bulb. The superior molecular lattice and corresponding strength of quartz is also capable of containing higher pressures, allowing Philips to increase the quantity of halogen gas in the bulb, resulting in increased light output and efficiency. Resistance to vibration is another key advance offered by quartz bulb construction. All these characteristics eliminate the risk of explosion while allowing Philips halogen headlight globes to perform better, glow brighter, operate more efficiently and generally last longer than lesser alternatives.

While quartz-glass has many properties which make it ideally suited for use in headlight globes, there is one property which works against it where a traditional hard-glass would shine.

Quartz-glass is comparatively sensitive to UV radiation, which bleaches the surface, resulting in an opacity and causing it to become brittle over time. Philips allow up to have our cake and eat it too by applying an anti-UV coating to the quartz used in their headlight globes. Philips call the resulting product, which sets Philips apart from the competition, UV-Quartz.

Philips have been leaders in automotive lighting for over a century, developing their first automotive lighting solutions not long after oil and acetylene gas lights joined the feathers chorus. Since then Philips have maintained a position at the forefront of automotive lighting development, introducing many technological innovations that have set the standards we are all now familiar with, amassing more patents than any other player in the space.

Today, Philips lighting are responsible for lighting more tarmac than any other manufacturer by a country mile, and serve as trusted supplier of lighting solutions to many of the world's leading automotive manufacturers.

More than two thirds of the cars leaving the factories in Europe don Philips products, and so too do half of the cars worldwide.

Philips Automotive lighting provide solutions for each and every automotive application. Whether you are after set of high beams, low beams, fog lights, indicators, stop lights, reversing lights, rear position or parking lights, license plate lights or even a cabin light, Philips automotive lighting has not just one but a range of solutions to suit your needs.
