Although xenon HIDs are the best option for those seeking the whitest headlight bulbs, there are plenty of white H7 bulbs options too. If you want halogen headlight bulbs that are a close colour match to factory-fitted xenon HIDs, you should choose Philips Diamond Vision. This range has a colour temperature of up to 5000K, giving you a bright
H7 Bulbs. H7 bulbs contain a single filament. H7 bulbs also come in white, blue, violet or yellow options. The most significant difference between the bulbs is the attachment. H7 bulbs fit different bulb sockets, having a two-pronged plug. Owner's manuals must be checked to determine type of bulb needed.
The light output is higher with H7 systems than with the H4 ones because two lamps interact. But since H7 systems require four bulbs instead of two, and bulbs should always be replaced on both sides at the same time because of their similar lifetime, H7 systems have a higher cost factor over time.
The main difference between the two bulbs is that the H11 connector has two narrow set prongs separated by a plastic tab compared to the 9005 (HB3), which has two wide set prongs. The H11 connector is also smaller than the 9005 and has tiny plastic tabs on each side of the plug casing. These differences can be observed in the image above
This ad implies that H7U bulbs have no UV filter, which is bad for the eyes and some plastics. The LED versions are H7 only, but would put out a small amount of UV light by design. After scanning many internet pages, the H7 (including LED versions) seem to dominate the ads. It would seem the H7U is being phased out due to high UV emissions.
A single filament bulb has one filament. Cars that have these types of bulbs use one for the high beam and another for the low beam. The most common type of bulbs used here are H1, H3, and H7. Double filament bulb. A double filament bulb has two filaments fitted in one bulb. The filaments allow the bulb to function as a high beam and low beam.
Vehicle system voltage. 12V. 12V. At first glance, it seems as though the XtraVision is actually a much better product. After all, it has a life expectancy of 850 hours compared to a measly 250 hours for the UltraStar. But that’s just one small part of the larger story. Remember that as we dig deeper into this.
Karun Technology offer all kinds of HID bulbs such as single beam bulbs, high and low beam bulbs, one xenon and one halogen bulbs. The most popluar items maybe H1, H3, H4, H7,H8, H9, H10, H11, H13
Whiter bulbs do not use any extra wattage. If you increase the wattage of a bulb you will notice a greater light output, but higher wattages tend to blow fairly quickly. This is why most bulbs run at a similar wattage. The higher Kelvin rating is achieved by either a blue coating on the bulb or a Xenon/halogen gas mixture.
Xenon headlights produce a bright light with a colour temperature between 4,000 – 6,000K. You can often distinguish headlights by looking at the beam pattern they produce. For example, if you turn your headlights on and they quickly beam yellow holding the same intensity, they are likely to be using halogen bulbs.
As you have already read, H7 bulbs emit light in the range of 2500-4000 lumens, while H11 bulbs emit around 1250 lumens. So, if we compare brightness, then H7 bulbs are definitely brighter. So, in case you need a brighter option for your car, choose H7.
Brightness. Brightness is one of the most noticeable differences between H11 and 9005 bulbs. H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
Don’t think that is the case as bulbs like H1 and H7 are single bulbs that work only on the beam they are plugged into. The other beam would be a separate bulb. 4200k/6000k is mentioned for these bulbs too.
Buy Replacement H15 Halogen Bulbs Here. This type of bulb using the PGJ23t-1 base is a dual filament bulb, this bulb is capable of producing a Hi / Lo beam pattern as is the H4 bulb. Many manufacturers have started to use the H15 Bulb to take care mainly of the DRL & Main Beam functions. There are many H15 LED and some H15 Xenon HID Bulb
