5Works like a charm

Works perfect and fast delivery to NL

GT Ultra Xenon D1S (Single)


These lamps replaced OEM Osram’s in my Cadillac just fine. Bulbs are bright as can be. Would highly recommend: far cheaper to buy two and ship 4-day than to buy one from big box auto (and you’ll likely wait a couple days because they’re not laying around in the store for immediate purchase).

5Good price. Great advice.

Made a phone call to power bulbs and was really impressed with the service and advice I received. My issue turned out to be the ballast, rather than bulbs but the 4k GT Ultra bulbs provided turned out to be clearer and brighter than the 6k (cheapo) bulbs I had before. Definitely on my list of trusted suppliers to order from again! Thanks.

All I can say is this company are superb to deal with. A problem with one of my bulbs was dealt with immediately. The bulbs themselves are really good, nice and bright and on a par With the osram xenarcs they replaced which to be fair were Still going after 12 years.

4Great Bulbs

I Assembled these bulbs about a week a go to Ford Mondeo Estate 2007. The product looked very well made at he assembly point as and during the 1st Night Drive it was clear that the vision with these bulbs was a lot clearer and white than with "normal market bulbs". So very good product. The only minus is the delivery time, within DHL, so there is no reason to pay extra for DHL, since it´s 13€ extra charge, but only few days quicker if any.

5works well

Perfect replacement for the 400$ cad, plus instalation, that the VW dealer wants. They work as well or better than oem.

5Xenon bulbs

Bought these bulbs for my Volvo XC60. Excellent product at very good price.Very quick delivery.

GT Ultra Xenon D1S (Single)


These bulbs are the perfect balance of performance and price. Very comparable to OEM—I’d say even slightly better—and roughly a quarter of the cost. Not sure on longevity at this point but as long as they last more than a year, they’ll be a cheaper solution.
