How bright is a light bulb?
Because the Lumen output from different manufacturers will vary. Here's a quick and easy guide to approximate total Lumen output.
Lumens | Watts |
| 2600 Lumens (lm) | 150W |
| 1600 Lumens (lm) | 100W |
| 1100 Lumens (lm) | 75W |
| 800 Lumens (lm) | 60W |
| 450 Lumens (lm) | 40W |
Understanding LED colour temperature and the Kelvin scale
Colour temperature 2000K to 3000K, the light produced is often referred to as a "warm white", "soft white", occasionally called a "candle white". It ranges from orange-ish to yellow-ish white in appearance. This kind of light is attractive, enjoyable, comfortable and relaxing.
Colour temperature 3100K to 4500K, the light produced is often referred to as a "neutral white", "bright white" or "natural white". Light sources within this range will emit a more neutral white light and may even have a slightly blue tint. This kind of light is bright, vibrant and clean appearing.
Colour temperature 4600K and above, the light produced is often referred to as a "cool white", "pure white" or "day white". Light sources in this range will have a blue-ish white tint to them. The higher the number, the more blueish it will appear. This kind of light will appear crisp, invigorating and energetic.
