BulbMatch: Light Bulb Color

Warm White or Soft White? Scan

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Point at a bulb that still works and get the answer in shopping words: 2700K warm white, 3000K soft white, 4000K cool white or 5000K daylight. One bulb goes. The other two still work. Which box do you buy? BulbMatch reads the light from a bulb that still works and names the bulb that matches it — 2700K warm white, 3000K soft white, 4000K cool white or 5000K daylight — in the words printed on the box. All on your iPhone: no account, no upload, no photo saved. ▸ A SHOPPING ANSWER, NOT A PHYSICS ANSWER Every other tool that reads light hands you a raw Kelvin figure and leaves the shopping to you. • "2700K — Warm White", and every phrase that bulb is sold under • Brands print "soft white" on bulbs of different temperatures — BulbMatch says so plainly and gives you the number to match instead • Confidence in plain English: steady and well clear of the next type, or a close call worth a second reading • When two types are genuinely in play it names both, instead of picking one to sound certain ▸ IT WILL NOT HAND YOU A NUMBER THAT IS STILL MOVING The button stays off until the reading holds still. • The live reading is greyed out until it settles — a jittering number is not an answer • "Frame too bright — the centre is clipping." "Frame too dark — nothing to read." It tells you what is wrong, not just that it failed • White-paper mode — light plain paper with that bulb alone and read the paper; it reads far tighter than pointing straight at a bulb • Four bulb types, never four digits — the camera's estimate does not support false precision, so the app does not print any ▸ SAVE THE HOUSE, NOT JUST THE ONE LAMP Measure a fixture once and the next bulb is a two-second lookup. • Rooms and fixtures — kitchen ceiling, 3 bulbs, E26, with a colour chip you can read at a glance • Copy a shopping list into Notes or Messages before you leave: Kitchen ceiling — 3 × 2700K (sold as "Soft White" or "Warm White"), E26 • Every reading kept per fixture, so you can see whether it was a close call • A reading taken on another iPhone is flagged — camera sensors disagree, and the app will not pretend otherwise ▸ ON YOUR IPHONE, FULL STOP There is no server to send anything to. • Works in airplane mode • No account, no sign-in, nothing to create • No photo is ever saved — frames are read and discarded • Privacy label: Data Not Collected ▸ FREE • Three measurements, with the full result and the confidence line • One saved fixture • White-paper mode ▸ ONE PAYMENT, NOT A SUBSCRIPTION BulbMatch Unlimited is a single purchase. There is nothing to renew and nothing to cancel, and it is family shareable — the person standing in the bulb aisle is often not the person who paid. • Unlimited measurements • Unlimited rooms and fixtures • Calibration — measure a bulb you already know and BulbMatch corrects for this phone's camera from then on • Shopping list you can take with you • The full reading history for every fixture BulbMatch is a guide for choosing a replacement bulb, not a laboratory instrument. It reads your iPhone's own white-balance estimate and reports one of four standard bulb types with a confidence band.
