The following table provides generic data on the popular lamp types that have historically been used both within the Illuma product ranges and also within the lighting industry in general. Many of these lamps are now being replaced by luminaires with their own integral LED and so a lamp is no longer required. We have reproduced this lamp table here by way of comparison to the light output of the integral LED luminaires detailed within the pages of this catalogue. LED luminaire characteristics including lumen output, beam angle, power consumption and colour temperatures are detailed in the relevant pages of the associated luminaire.
A measure of the light source’s ability to render the colours of objects as similar to those under a reference light source.
A descriptive term for the appearance of light expressed in Kelvin.
2700K - Extra Warm White, 3000K - Warm White,
4000K - Neutral White, 6000K - Pure White
| Ra | Group | Typical Application |
|---|---|---|
| 90-100 | 1A | Where accurate colour rendering is required (colour matching) |
| 80-89 | 1B | Where good colour rendering is required (accurate colour judgements) |
| 70-79 | 2A | Where moderate to good colour rendering is required |
| 60-69 | 2B | Where moderate colour rendering is required |
| 40-59 | 3 | Where colour rendering is of little significance but marked distortion of colour is unacceptable |
| 20-39 | 4 | Where colour rendering is unimportant |
