DMEX Best D4S HID Headlight Bulbs
Overall Best
The moment I switched on this DMEX HID, I was blown away by the brilliance of the light it threw out, completely outshining the stock bulbs I’d been used to. With one of the crispest color temperatures among all HIDs I’ve tried, it was clear these bulbs were built to last.
With a blazing beam of light pouring out 3700 lumens, I instantly felt more at ease driving at night. These HIDs are a quantum leap over stock halogens, and when I stack them up against other HIDs, they’re still powerfully bright.
What stood out about these bulbs, besides their raw brightness, was how much further and wider they projected. This broader scope dramatically improved my road coverage. I found myself noticing not only more of the road but also the details of what I could already see. Everything appeared clearer, more sharply defined.
And that’s not only down to the sheer intensity of these bulbs, but also their remarkable color profile. The 6000K color temperature produced a near-perfect white light, boosting my visibility and making it easier to identify different road features. Whiter beams tend to be more reflective, which meant I could spot road signs, other vehicles, pedestrians with much more ease and speed.
But these bulbs weren’t just about high performance. They also promised, and delivered, outstanding durability. Armed with high-quality quartz anti-UV glass, APL pills to extend their lifespan, and a tungsten metal electrode, these bulbs pack in features that add up to a whopping 3500-hour lifespan, leading their class.

BEST BUDGET
As soon as I installed the SUHU Diamond’s D4S headlight bulbs, I felt like I had taken command of the budget HID category, their potent light output, variety of color temperatures, and long-lasting construction just blew me away.
Firing up these HIDs, I was welcomed by a brilliant 3200 lumens, clearly outclassing the stock bulbs I’d grown used to. What left me equally captivated was the expansive projection and the far-reaching light they emitted. It was as if the path ahead was painted more vividly for me to follow.
Though these bulbs come in a variety of color temperature options, I found myself drawn towards the cleaner, whiter 6000k instead of the standard 4300k or the blue-tinged 8000k. The pure white beam was a boon for my nighttime drives, helping me spot sudden hazards like wildlife crossing or the sudden brake lights of other vehicles.
The beam pattern? Smooth and steady, with not a dark spot in sight. The absence of flickering made for a more pleasing view, with a beam that was sharp and well-directed.
When it came to resilience, these bulbs set a new standard for the budget category. With an IP68 weatherproof rating, I had the confidence these HIDs could brave both the rain and the snow. Their construction featuring high-grade metal and glass further reassured me of their durability. The ingenious temperature management design was the icing on the cake, ensuring the internal components stay protected.
Speaking of longevity, the manufacturers promise these HIDs will last over 3000 hours. Though it’s not the longest lifespan I’ve seen, it’s leaps and bounds ahead of stock bulbs and quite a feat for the price.
