How we supply it: LED lights and fittings are arranged through a partner electrical dealer who quotes, supplies and bills them and pays us a referral commission. Give the dealer your ceiling plan with the colour temperature per room; fittings arrive after the false ceiling and painting are done.
In one line: An LED light is a lamp or fitting that makes light from light-emitting diodes driven by an electronic driver, rated by lumens (light output), colour temperature in kelvin and colour rendering index (CRI).
Colour temperature by room
| Light | Kelvin | Rooms |
|---|---|---|
| Warm white | 2700–3000 K | Bedrooms, living and dining |
| Neutral (natural) white | About 4000 K | Kitchen, bathroom, study |
| Cool daylight | 5700–6500 K | Utility, store, parking |
Reading an LED box
An LED light is a lamp or fitting that makes light from light-emitting diodes driven by an electronic driver, rated by lumens (light output), colour temperature in kelvin and colour rendering index (CRI).
Watts only tell you the power drawn. Two 9 W bulbs can differ widely in lumens; a CRI of 80 or more shows skin and food colours naturally.
Fitting types
| Fitting | Where | Note |
|---|---|---|
| Bulb (B22 base) | Existing holders, small rooms | Easy replacement |
| Batten | Bedrooms, kitchen, utility | Replaces the tube light |
| Panel (recessed or surface) | Living, bedrooms, false ceilings | Even, glare-free light |
| Downlight or spotlight (COB) | False ceilings, accents | Needs ceiling depth |
| Strip light | Cove in a false ceiling | Indirect glow |
| Outdoor or flood light | Balcony, gate, compound | IP65 or higher |
Lumens per room
Typical estimate: about 150–300 lumens per m² for general rooms and 300–500 for kitchens and study desks; LEDs give roughly 100 lumens per watt.
- 12 × 12 ft bedroom (about 13.4 m²): roughly 2,000–2,700 lumens, about 20–27 W of LED
- Kitchen of 10 × 8 ft (about 7.4 m²): roughly 2,200–3,700 lumens
- Add task lights over the counter and desk rather than over-lighting the whole room
Checks on LED lamps and fittings
- LED lamps should carry the BIS registration (R-number) and IS 16102 on the box.
- The box should list lumens, colour temperature and CRI, not only watts.
- Keep one colour temperature per room; mixing 3000 K and 6500 K looks patchy.
- Point a phone camera at the lit fitting: dark rolling bands suggest flicker.
- Outdoor fittings should be marked IP65 or higher.
Timing and storage
- Fix fittings after the false ceiling and painting are done; keep them boxed until then.
- Store drivers dry.
- Write the colour temperature on each box so replacements match.
Lighting mistakes
- Buying by watts instead of lumens.
- Cool daylight everywhere, which makes bedrooms harsh at night.
- Downlights cut into a false ceiling without checking the depth behind it.
- Indoor fittings on rain-exposed balconies.
- One switch for every light in a large hall.
