OSRAM Cool Blue Hyper+ Halogen Review
An unusually cool 4,700K halogen for appearance-focused buyers, with severe output losses, no recorded lifespan result, and a higher price than the better-balanced Cool Blue Advance.

Our verdict
Cool Blue Hyper+ delivers a conspicuously cool 4,700K halogen appearance, 1,275K above the OSRAM Original reference. That style comes with about 45% fewer total lumens and large losses in every reflector and projector measurement. With a $35–49 estimated price and no recorded lifespan result, it is difficult to recommend over Cool Blue Advance unless the additional color shift is the main requirement.
What we liked
- The 4,700K result is one of the cooler measured halogen colors.
- It retains conventional 55-watt halogen installation.
- Seven recorded bulb sizes cover several common applications.
What to consider
- Reflector low and high beam measure about 29% and 31% below the reference.
- Projector low and high beam trail by roughly 18% and 37%.
- Lifespan is not recorded, and the estimated $35–49 price is high for the measured output.
A conventional extreme-color halogen
Cool Blue Hyper+ is a conventional 55-watt halogen bulb, not an HID or LED conversion. It does not require ballasts, external drivers, cooling fans, heat sinks, or conversion wiring.
The current record lists 9003, 9005, 9006, H1, H3, H7, and H11. That range does not confirm exact-vehicle fitment; verify the bulb code, socket, housing, seating, regional version, and aim.
OSRAM uses several similar Cool Blue names. Confirm the exact Hyper+ product and avoid mixing it with Cool Blue Advance, Cool Blue Intense, or D-series HID products.

The extreme color shift costs light
Both reflector measurements fall more than 25% below the standard halogen reference.
About these tests: Measurements come from BulbFacts reference housings for consistent product comparison. They are not exact-vehicle results; seating, optics, lens condition, and aim can change real-world output.
Gray dots show every scored bulb. Named markers are current BulbFacts recommendations. The 5.0 reference is a baseline, not a maximum.
Reflector performance score 0.7 compared with 83 scored halogen bulbs and the 5.0 reference baseline.
- Low-beam hotspot
- 266 luxper bulb
Reflector low-beam output of 266 lux compared with 83 halogen bulbs.
- High-beam output
- 602 luxper bulb
Reflector high-beam output of 602 lux compared with 83 halogen bulbs.
- Reference low beam
- 373 lux
- Reference high beam
- 876 lux
- Reference color
- 3,425 K
- Reference output
- 1,564 lm
The 266-lux low beam and 602-lux high beam are also slightly below Cool Blue Advance at 273 and 618 lux. Neither bulb is an output upgrade, but Advance gives up less light.
The 0.7 reflector score confirms that Hyper+ should be treated as an appearance choice only.
Projector high beam drops 37%
The projector low beam remains closer to the reference than the high beam, but neither result supports a visibility-upgrade claim.
Gray dots show every scored projector result. Named markers are current BulbFacts recommendations. The 5.0 reference is a baseline, not a maximum.
Projector performance score 0.8 compared with 82 scored halogen bulbs and the 5.0 reference baseline.
- Low-beam hotspot
- 232 luxper bulb
Projector low-beam output of 232 lux compared with 82 halogen bulbs.
- High-beam output
- 591 luxper bulb
Projector high-beam output of 591 lux compared with 82 halogen bulbs.
Cool Blue Advance measures 243 low lux and 648 high lux in the same projector reference. Cool Blue Intense is less white at 3,800K, but much stronger at 291 low lux and 1,111 high lux.
The 0.8 projector score leaves Hyper+ near the styling end of the chart rather than the performance end.
Cool white color with a steep lumen cost
The 4,700K result is the product’s defining strength; the 859-lumen result is the central tradeoff.
OSRAM Cool Blue Hyper+ Kelvin
OSRAM Cool Blue Hyper+ lumens
We measured 4,700K, 1,275K above the OSRAM Original reference at 3,425K. That is a conspicuous shift toward a modern white appearance and 350K cooler than Cool Blue Advance.
Total output measured 859 lumens per bulb, 705 lumens or roughly 45% below the 1,564-lumen reference. The whiter appearance must not be confused with greater measured brightness.
Lifespan, fit, and value
The current record does not include a completed lifespan result, so the ownership case rests on color, price, and fitment rather than durability claims.

Unknown life weakens the value case
The current chart records lifespan as N/A. That is an unknown, not a zero, and this review does not convert it into an estimate from warranty, price, or another Cool Blue product.
The estimated price is $35–49. Cool Blue Advance sits at $20–34, produces slightly more measured light, and carries a 5.7-year estimate, making it the safer color-focused purchase.
Recorded sizes and vehicle fit
The chart records 9003, 9005, 9006, H1, H3, H7, and H11. Verify the exact bulb type, product version, socket, housing, and vehicle guide before ordering.
Should you buy it?
Buy OSRAM Cool Blue Hyper+ only when its conspicuously cool 4,700K halogen appearance is the overriding goal and the measured output loss is acceptable.
Skip it when visibility, value, or known longevity matters. It trails the reference in every beam measurement, produces about 45% fewer lumens, costs an estimated $35–49, and has no recorded lifespan result.
Cool Blue Advance is the better-balanced white-look choice. Hyper+ is the more extreme color choice, not the better overall bulb.
If that extreme color tradeoff fits your vehicle and priorities, check the current price or compare the complete chart before deciding.
