OSRAM Cool Blue Hyper+ vs OEM Halogen Bulbs
OSRAM Cool Blue Hyper was originally tested as one of the best xenon-look halogen bulbs. Current BulbFacts data still shows a cool white appearance, but the measured output penalty is severe.
Quick Take
Cool Blue Hyper+ is a style bulb, not a visibility bulb. Current data shows a cool 4700K color, but reflector and projector output are both far below the reference bulb.
Current Chart Snapshot
- Reflector score: 0.7, with 266 low lux and 602 high lux.
- Projector score: 0.8, with 232 low lux and 591 high lux.
- Measured color: 4700K, much whiter than the 3425K reference.
- Estimated lifespan: N/A, with an estimated $35-49 price range in current data.

The original review compared the OSRAM Cool Blue Hyper against basic OEM-style bulbs for brightness, whiteness, and cost. Back then, it was treated as one of the strongest xenon-look halogen options, especially compared with Philips Diamond Vision.
Current chart data keeps it in the white-look category, but the recommendation needs more caution. It is not a bulb I would choose for more usable road light. It is mainly for someone who wants a cooler halogen appearance and understands the output loss.
Cooler color with a major reflector output penalty
In reflector headlights, Cool Blue Hyper+ gives up a large amount of measured light compared with the reference bulb.

OSRAM Cool Blue Hyper+
Current reflector data shows a 0.7 score, 266 low lux, 602 high lux, 4700K color, and 859 lumens. The white look is clear, but output is very weak.

Philips Diamond Vision
Diamond Vision is even whiter at 5500K, with 268 low lux and 595 high lux in reflectors. Both bulbs are style-first choices with poor output.
In the original article, Cool Blue Hyper was described as about 38% dimmer than basic stock bulbs, but with a very white xenon-style color. Current reflector data still supports the output warning. Against the OSRAM Original reference at 373 low lux and 876 high lux, Cool Blue Hyper+ measures only 266 low lux and 602 high lux.
That is a big drop in usable light. It is roughly in the same performance neighborhood as Philips Diamond Vision, which measures 268 low lux and 595 high lux in the current reflector chart.
The old article measured about 5240K. Current data shows 4700K, still much cooler than the reference bulb but not as cool as Diamond Vision's 5500K.


Projector output is also weak
In projector-style halogen headlights, Cool Blue Hyper+ currently scores 0.8, with 232 low lux, 591 high lux, 4700K color, and 859 lumens. Compared with the OSRAM Original projector baseline of 284 low lux and 935 high lux, it loses output in both beams.
If your vehicle uses projector-style halogen headlights, this is not a good upgrade for visibility. OSRAM Cool Blue Intense is much less white at 3800K, but it is far more usable in current data with 291 low lux and 1111 high lux in projectors.
High style cost, low output return
The current chart shows Cool Blue Hyper+ with an estimated $35-49 price range and N/A lifespan data. That makes the value case tough, because you are paying more for a bulb that gives up a lot of measured light.
The only real reason to choose it is appearance. If you want a cooler halogen look and accept the visibility penalty, it does that. For normal driving, choose a performance halogen or at least a more balanced white-look bulb.


A white-look bulb, not a visibility upgrade
OSRAM Cool Blue Hyper+ gives a noticeably cooler halogen look, but the current BulbFacts chart shows a major output penalty in both reflector and projector headlights.
If you are chasing appearance only, it belongs in the conversation with Philips Diamond Vision. If you want better night driving, skip it and compare the current recommended halogen bulbs instead.
