DANGER
Always isolate power before touching wiring. If you smell burning or see smoke, stop and call Roy immediately.
The Kelvin Scale: Warm vs Cool White
Color temperature is measured in Kelvin (K). Lower numbers mean warmer, cosier light; higher numbers mean cooler, brighter light.
- Warm White (2700K–3000K): Best for living rooms, bedrooms, and cosy spaces. Mimics old incandescent bulbs – soft, amber tones.
- Cool White (4000K–5000K): Best for kitchens, bathrooms, and task areas. Crisp, daylight-like, helps visibility for cooking and grooming.
Tip: Keep the same color temperature throughout a room for consistent ambience.
Wattage vs Lumens: The Conversion Table
Old bulbs were rated in watts; LEDs are much more efficient. Use lumens (lm) to judge brightness. Here's a simple guide:
| Old Bulb (Watts) | New LED (Watts) | Brightness (Lumens) |
|---|---|---|
| 40W | 4–5W | 450 lm |
| 60W | 7–9W | 800 lm |
| 100W | 12–14W | 1600 lm |
Example: A 6W LED typically replaces an old 60W bulb (around 800 lm).
Dimmer Warning
If you have dimmer switches, always check for the "Dimmable" label on the bulb. Non-dimmable LEDs on dimmers can flicker, buzz, or fail prematurely. For dimmer circuits, use bulbs marked "Dimmable" and ideally "Trailing edge compatible" if you have older dimmers.
