Colour Temperature Explained
ULTRABEAM produces 6500K daylight white — the gold standard for workshops and detail work.
What Is Colour Temperature?
Colour temperature describes the warmth or coolness of light. It’s not about heat — it’s about how yellow or blue-white the light appears to your eyes.
- Colour temperature is measured in Kelvin (K) — lower numbers are warmer (yellow), higher numbers are cooler (blue-white)
- 2700K (warm white): the yellowish glow of a traditional incandescent bulb — cosy but poor for seeing detail
- 4000K (neutral white): a balanced tone used in offices and retail — neither warm nor cool
- 6500K (daylight white): mimics natural midday sunlight — the brightest, clearest light for work environments
Pro tip
Think of it like a spectrum: candlelight is ~1800K (very warm orange), sunset is ~3000K, and bright midday sun is ~6500K. ULTRABEAM sits at the daylight end.

ULTRABEAM produces 6500K daylight white — close to the cool end of the scale, matching natural midday sunlight.

Why 6500K?
Work environments need light you can actually work under. 6500K daylight white is the industry standard for spaces where you need to see clearly and judge colours accurately.
- True colour accuracy: see paint finishes, wiring colours, and surface imperfections as they really are
- Maximum alertness: daylight-spectrum lighting keeps you focused and alert during long workshop sessions
- No yellow cast: warm lighting makes everything look yellowed — 6500K shows colours accurately on painted surfaces, car panels, and products
- Industry standard: professional workshops, detailing bays, and commercial garages all use 6500K for a reason
Pro tip
If you’ve ever tried to match paint colours under warm yellow lighting and got it wrong — that’s exactly the problem 6500K solves. What you see under ULTRABEAM is what you see in daylight.
Real-World Difference
The practical difference between warm and daylight lighting is dramatic in a working environment. Here’s what 6500K means for common tasks.
- Car detailing: spot swirl marks, orange peel, and colour depth that warm lights completely hide
- Woodworking: see grain patterns and sanding scratches that determine finish quality
- Electrical work: clearly distinguish wire colours — critical for safety with red, blue, yellow, and green wiring
- General workshop: reduce eye strain during long sessions — your eyes work less hard under daylight-balanced light
Pro tip
Car detailers call 6500K lighting non-negotiable. If you’re doing paint correction, ceramic coating, or even basic detail work, daylight lighting is the single biggest upgrade you can make.
Colour Temperature Questions
For a living room, maybe. For a workshop or workspace, it’s exactly right. 6500K matches natural daylight — it only feels harsh if you’re comparing it to dim warm bulbs. Once you work under proper daylight lighting, you won’t go back.
Yes, positively. Daylight-balanced lighting shows your tile colours as they truly are. Under warm lighting, greys look brownish and blues look muted. Under 6500K, you see the actual colours you chose.
Mixed colour temperatures create uneven lighting zones — one area looks yellow, the other looks blue-white. For best results, commit to one temperature throughout the space. Most people replace their old warm lights entirely once they see the ULTRABEAM difference.
