GT Ultra 120 H4 (Twin)

The new GT Ultra 120 gives you the chance to experience a vastly superior light output from your headlights at a reasonable price.

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.

4 T6 bulbs

Bought these to upgrade the stock bulbs on my T6 transporter which were hopeless. These have improved visibility at night compared to the originals.

5 GT Bulbs...

As these received consistently good marks in the auto express bulb tests I bought them, packaging is OK, bulbs are nice and bright, I believe they are quite equally balanced from when I angle them down to see the beams, but not too dazzling for other drivers.

4 GT Ultra 120 H4 (Twin)

Came across this company after being mentioned in an Australian 4x4 forum. Since auto parts can be quite expensive here I thought I would purchase a brand of bulbs I hadn't heard of before and try them out. Dealing with the supplier is very straight forward. The item was dispatched promptly and delivered within the time frames advertised. I have yet to install the bulbs so I can't comment on the quality, but I would have no hesitation in dealing with PowerBulds in the future

5 Great service as usual

I now use Powerbulbs as y go to site for vehicle lighting. The two for one GT bulbs offer makes for great savings. The excellent service is a rare treat these days.

Have only used them a handful of times so far but the difference between these and my old globes is literally night and day. For the price these are with the 2 for 1 special its a no brainier really. Thumbs up for me

5 Fantastic bulbs, fantastic price!

Took advantage of the “buy one, get one” and purchased these for my 05 Toyota Landcruiser Prado and 2003 Toyota Camry Altise. The shipping to Australia was reasonably quick. The difference is as expected with these 120% globes from the standard halogens I had in them, cannot fault the quality so far. For the price, and 20% off already currently, I’ll definitely be getting these again when they start to go.

5 Superb

Marvellous, gives out great light, thanks

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 $25 for a single globe. I bought a twin pack for $29 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.

By Glenn L on

GT Ultra 120 H4 (Twin)

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.

5 Brilliant GT ultra bulbs Bogof

Ultra quick delivery good price and as good as more expensive top branded bulbs I've replaced with them in my van and will put the other pair in my daughter's car as she is complaining her headlights are like candles. I am now going to order more as I need to keep spares for my van.
