Why buy the GT Ultra 120 H4 (Twin)?

Using only Original Equipment Quality parts, the GT Ultra 120 is manufactured to precise German design specifications and standards. The GT Ultra 120 is a fantastic choice for drivers wanting to massively enhance their on-road visibility and vision.

The innovative design of the GT Ultra 120 allows for brilliant illumination that projects up to 120% more light than a standard halogen bulb, reaching up to 35 metres farther while remaining perfectly road legal and reliable. This intense, expansive light output is conducive to a much safer, more comfortable drive as potential hazards appear much sooner on the road, while other drivers benefit from your heightened presence.

Where most headlight bulbs offering extra style forfeit their road legality as a result, the road-legal GT Ultra 120 range offers the slightly enhanced style of a 20% whiter light with a colour temperature of up to 3800K. As such, the GT Ultra 120 gives you the chance to enjoy increased sight and safety without sacrificing style.

Experience the many benefits of the GT Ultra 120 today.

5 Great bang-for-the-buck

These bulbs perform very well, being noticeably brighter than the stock bulbs. More importantly, the beam pattern is much better - wider and longer reaching. Although not a "big name" brand, the bulbs claim German design, and are marked as being made in Korea. This indicates that they are of decent quality. At the "buy one get one" price they're a steal, and I got them with a 20% off coupon to boot. Tracked delivery to the Philippines took about three weeks. Local post office is notoriously unreliable, so I have nothing to complain about in this respect.

5 Good brands and a great service

This was my 2nd purchase from Powerbulbs and like the 1st I couldn't be happier. Here in Australia the auto shops charge for a single globe. I bought a twin pack for and got another twin pack for free and free postage.And quick too. As well as that the lights are a lot brighter than my old ones so I am a big fan. Not sure how the rating number work.I gave a five which is meant to be the best.

5 Pretty Good!

What can I say. Better than originals for output (less yellow light) & the price, you can't go wrong. They even work in Oz.Yes, I recommend these globes.

5 Very Good Lamps & Service

Needed a new headlamp and did a bit of googling and very happily stumbled upon PowerBulbs. By far the best range and lowest prices on the web. Especially with this particular lamp, that's super bright whilst still full street legal unlike many others, being a BOGOF deal. So for the price of a single lamp from other e-tailers and physical stores I got FOUR!! Just brilliant.
