Which is better, NIGHT BREAKER or SILVERSTAR or COOL BLUE?
This all depends on personal requirements and preferences. Safety-conscious drivers who are looking for maximum performance and as much light as possible on the road ahead tend to choose OSRAM SILVERSTAR lamps with up to 50% more light than a standard lamp - or even better the NIGHT BREAKER range of headlight lamps.
OSRAM NIGHT BREAKER are the best possible choice at present for halogen headlights, because they offer the highest light output with up to 90% more light on the road an an up to 35m longer beam.
Drivers who prefer good performance, high visibility and something a little different tend to choose lamps from the OSRAM COOL BLUE range.
The idea is that you are safer in a car that is noticed.
Of course, all these product ranges are fully ECE approved without restrictions for use on roads throughout Europe.
Why do headlight bulbs have to have reduced UV emission?
More and more headlights are now being manufactured with plastic components to save on weight and cost.
Especially, almost all the clear headlight covers on new cars these days are made of plastic.
The effect of UV radiation from light sources or from the sun on transparent plastics is well documented; over a lengthy period of time the plastic turns yellow and brittle, and this process is speeded up by high material temperatures.
OSRAM UV-Filter bulbs comply with the statutory regulations of ECE Standard R37 (except off-road lamps) with regard to UV thresholds and can therefore be used without restriction in plastic headlights.
This property is indicated on the packaging by the "UV FILTER" symbol. On the bulb itself you will see the letter "U".
All OSRAM halogen headlight bulbs are UV-Filter lamps.
Is there an incandescent (halogen) bulb that will last forever?
The laws of physics dictate that there is no such thing as an incandescent (halogen) bulb that can last forever. When current flows through a filament some of the filament inevitably vaporizes. After a while this results in the filament burning out.
It is possible to design an incandescent bulb so that it lasts a long time. However, there is always a compromise involved because the luminous efficacy is reduced (i.e. the amount of light that can be generated from a particular input power). The filament can be operated at a lower temperature, or a thicker filament can be used, so that it takes longer for the filament to vaporize and burn out.
An important consideration is safety. Bulbs with an extremely long life would not meet current requirements for headlights. Because they would not generate sufficient light output to make a satisfactory beam pattern.
Beware of cheapo bulbs that have no UV coating and etc.... might fry your connectors and cause the coating on the reflectors to flake off.
Osram Cool Blue (slightly whiter than stock but still yellow, rated at 4000K, LTA approved)
Osram Silverstar (same colour as stock but up to 50% brighter, LTA approved)
Osram Cool Blue Hyper (pure white with a bluish tingue rated at 5000K, not approved)
Osram Cool Blue Mega (less white than Hyper, rated at 4300K, not approved)
Osram Night Breaker (10% whiter than stock but up to 90% brighter, LTA approved)
Comparing Night Breaker and Cool Blue 4000K, both colour are almost similar but in terms of brightness, Night Breaker is much better.Look wat happened to a al' cheapo bulbs used by one of my customers.....As u can see, the glass surface was bloated up ... just imagine what will happen if the glass were to melt or even worse, explode within the headlamps?
