OSRAM COOL BLUE BOOST H4, halogen headlight lamp, 62193CBB-HCB, 12 V passenger car, duobox (2 units), Duo Box

I brought these lamps for my 2017 Hyundai Tucson as the lamps (Dipped beam and Static cornering) are standard Halogen and fairly poor (shame) as the actual car is fantastic. Halogen lamp are generally a low cost option for manufacturers, and widely used although giving poor light levels in comparison to todays standards. Many aftermarket companies now offer lamps that claim their lamps are brighter, some between 30-100%, also a range increase (up-to 75m), and options to give Xenon or blue effect which is only cosmetic. After several purchases I brought these Osram cool blue boost H7 and I'm very impressed, traditionally minimum and maximum brightness has been measured on wattage or how much energy the lamp uses although these seem outdated (The road vehicles lighting regulations 1989), there is no maximum wattage for headlights the problem is glare. I have used these lamps in a elliptical projector unit which has a shield keeping the light emitted at a low level preventing high level glare protecting oncoming drivers being dazzled, that aside they are superb giving an almost white light (5000k) and an increased range, the claimed 50% light increase is not far off, overall of the several branded lamps purchased these are far superior in all aspects and I would highly recommend this product 5*

Delighted with these - they are really white and bright

After forking out for the osram night breakers 200s to have one blow after four months, decided on these....Cheaper all round with the same if not slightly better light output....Not as white as the night breakers but standard looking with a good distance of beam pattern to boot....

So, story time... bought myself some COB LED sidelights for my lil RAV4, put them in and were beautiful blue, my OG headlight bulbs.. noticeable not. So researched as much as i could for both legality, Kelvin measures and good quality bulbs that also have a noticeable blue/white tint to match my sidelights. Came across these! Personally i love them, they give the exact look i was after. For on the road in my opinion they work very well. Going from OG halos to these i feel a little more comfortable and confident in dark conditions. I also tried them in rain, i can say a little lacking in heavy rain but not enough to say unusable. (Could also help that i have bumper mounted fog lights to increase visibility) but over all im very impressed, the style, the quality and the road use.For anyone whos concerned about "off road use" i wouldn't worry, as long as your lights are adjusted/angled appropriately (i.e. not pointing AT other drivers) your fine. In the UK headlights can go upto 6000K before being questionable.Also, for anyone not aware DO NOT touch the bulbs with your bare hands.

Super

Not far off LEDs and even though they are technically not road legal you’re never gonna get pulled up on it. Match my led side lights perfect

Finally a set of halogens that ARE 100% WHITE! With a slight blue tint. They look superb, far better than the many others I have tried. As for night time driving I don't do alot at the moment as its summer and the days are long so i can't comment on how well they perform in terms of range and coverage. I purchased these purely for looks. I will edit later in the year when the long dark nights are here.Edit - 6/11/19.So in terms of performance these bulbs are simply terrible, I leave for work at 5.30am and finish 6pm so most of my driving is now in the dark. When it's wet and raining these bulbs are almost dangerous, you can't see a thing. If your driving in a well lit urban area with street lamps you can hardly tell they are on! I'm almost tempted to say they are worse than stock halogens. With that being said they still look the part don't get me wrong and have lasted a good 5 months so far so I'm happy with that side but performance wise they are simply not good enough. I've gone back to the philips xtreme vision which in my view are the best performing halogen bulbs you can get for use in reflector headlights. I tried them in my wife's projectors and they are slightly better but I decided to use LEDs for hers. Don't get me wrong I will use them again in the summer for their looks but for now I'll just stick with the philips as they out do these by a mile.

The bulbs are amazing, I drive dayly nights and day, my lights are aways on and the bulbs survived for about 4 months, lifespan is about 500h,the visibility is good, light is perfect, distance is OK as well even though my headlight unit isn't the best only time I felt the lights are weak was during rains in city conditions where almost all the roads are light up, so wouldnt even concider that as a downside
