Installation on motorcycle...successful. The light is warm white and intense. Visibility is very good. I have no opinion on the lifespan since I installed it relatively recently!

Excellent bulbs, much better light than the factory ones, I have bought them again and I will choose them again when needed.

Very good lighting, but they didn't last even a year, both burned out without having used them enough!

Important for anyone considering buying them: They are not stronger than the mama! They simply offer much better (in my opinion) color in the light. Don't expect the night to become day in terms of brightness. They are equivalent to the factory ones. Despite all this, I like them and I bought them for my second car after trying them for about a year. I recommend them

After 2 sets of Philips +130%, I installed the +150% and I notice a noticeable difference in the headlights and a significant difference in the high beam. The color is not white, but I didn't expect it to be and I am not disappointed. If you want white light, put your hand in your pocket and change the lighting fixtures. In terms of performance, I am very satisfied, but I will come back regarding durability.

I initially bought the cheapest version of the crystal, but I didn't like them at all. They didn't illuminate and so I went and bought these ones, and I am very satisfied. They are much better and illuminate much better as well

A thousand times LED or xenon...... whoever wants them, I give them away..... excessively small difference from the original.... burned out exactly in three months

Owner here for 5 months with the racing bulbs, I have to say that they are generally good bulbs. The color temperature they emit is at 3700 kelvin, which means they are slightly whiter than the original Philips bulbs, but they have no comparison to the pure white light of xenon.

Also, the claim of being 150% brighter than the original is not true, it's purely a marketing issue. I believe with the racing bulbs, I gained an additional 30% in brightness. The reasons why I gave 4 stars instead of 5 are two.

1. Short lifespan of 200 to 250 hours.
2. In low beam, it emits 1100 lumens, which is the same as the original bulbs, in other words, it doesn't illuminate the road intensely at a low level. However, in high beam, it performs very well and emits 5100 lumens, while the original emits 4200, which means the beam reaches further.

Very good bulbs if you don't have xenon or LED lights. The difference compared to the slightly cheaper model from Philips is not enough to justify the price. Otherwise, excellent performance.

Perhaps the best bulbs in terms of brightness with pure white light! No comparison to the factory ones. The only disadvantage is the relatively short lifespan. 250 hours compared to the rest of the same company's bulbs, which have 400 hours. Hence the 4 stars.
