Colour Temperature Explained
ULTRABEAM produces 6500K daylight white, the gold standard for workshops and detail work.
The short version
- Kelvin measures light colour: low is warm yellow, high is blue-white daylight.
- ULTRABEAM is 6500K daylight white, the workshop standard.
- Under 6500K you see true colours, no yellow cast.
What Is Colour Temperature?
Colour temperature describes the warmth or coolness of light. It measures how yellow or blue-white the light looks to your eyes, not how hot it is.
- Colour temperature is measured in Kelvin (K), lower numbers are warmer (yellow), higher numbers are cooler (blue-white)
- 2700K-3000K (Warm White): the amber glow of a living room or bedroom, inviting, but it softens every colour it touches
- 3500K-4000K (Neutral White): the balanced tone of a modern kitchen or office, crisp enough for reading but still slightly warm
- 4000K-5000K (Cool White): the clear, wide-awake light of a commercial space, sharp for task work without the full intensity of daylight
- 5000K-6500K (Daylight): the cool, high-clarity light of midday sun, where detail work happens and colours look true
Pro tip
Picture the spectrum end to end: a bedside lamp sits around 2700K, a bright kitchen at 4000K and the midday sun at 6500K. ULTRABEAM delivers that daylight clarity indoors.

Four zones of light, from the amber warmth of a lounge room to the clear, revealing output of natural daylight.

Why 6500K Is the Workshop Standard
Work environments need light you can actually work under. 6500K daylight white is the industry standard for seeing clearly and judging colours accurately, and it transforms real tasks.
- True colour accuracy: see paint finishes, wiring colours and surface imperfections as they really are
- Maximum alertness: daylight-spectrum lighting keeps you focused during long workshop sessions
- No yellow cast: warm lighting yellows everything, 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
- 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 tell wire colours apart, critical for safety with red, blue, yellow and green wiring
- General workshop: less eye strain on long sessions, your eyes work less hard under daylight-balanced light
Pro tip
Car detailers call 6500K non-negotiable. If you have ever matched paint under warm lighting and got it wrong, that is the problem daylight lighting solves. What you see under ULTRABEAM is what you see in daylight.
Colour Temperature Questions
For a living room, maybe. For a workshop or workspace, it's exactly right. 6500K matches natural daylight, so it only feels harsh if you are 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.
