The full sequence we run with clients: location, mounting, optics, power, protection, control, packaging, tolerance. One decision per line — copy it into your RFQ.
A 1 m viewing distance needs 320-480 LEDs/m or COB. A room-scale wash works with 120-160 SMD. The viewing distance decides density before the budget does.
8 mm or 10 mm board for a standard 30 mm cove; 5 mm where the reveal is tighter than 20 mm. Aluminium channel doubles as the heat sink — the cheapest optical and thermal upgrade you can buy.
Warm 2700K for hospitality and bedrooms, neutral 4000K for kitchens and circulation, cool 5000K+ for industrial. Ra90 minimum where products are sold, Ra95+ for jewellery, art and cosmetics.
10 W/m is the safe default for enclosed voids; 14-15 W/m only when there is a heat path. Total watts = metres x W/m; from that everything downstream is arithmetic.
DC24V is the default: it halves the voltage-drop budget versus 12V and allows 5 m feed spans. Split long runs and feed from the middle.
IP20 dry interior; IP65 splash zones and damp rooms; IP67 sleeve or IP68 potted for rain, burial and immersion. The rating applies to the whole assembly, ends included.
Fixed white for most projects. Dimming needs a driver that matches the protocol: trailing-edge/PWM, 0-10V, DALI or DMX. The dimmer and the driver are one decision, not two.
Fix reel length, connector type and label format. Write acceptance tolerances (CCT range, CRI minimum, lm/m minimum) into the PO, and order 5% spares from the same batch.
Built entirely to your specification: PCB layout, LED type and density, CCT, CRI, voltage, power, IP rating, connectors, labeling and packaging.
