High CRI bulbs for Coffee Roasting and Production
I recently purchased a case of bulbs from you and I am curious about how to adapt the lighting in a roasting space. Color is very important for coffee roasting so I am looking for a high CRI value bulb, but the ones I tend to get are not very "bright" or it seems dim in the space. Does the "K" value affect this?
We're happy to confirm that the color temperature value is not tied to the CRI value or brightness. The brightness of the light emitted by a bulb is measured by the lumen output, whereas the color temperature measures how 'warm' or 'cool' the light appears to be. On the other hand, CRI measures how similar the light output is to that of natural sunlight.
While you may find that higher CRI products have a lower lumen output than traditional incandescent bulbs, the higher CRI bulbs have the benefit of offering light that has a similar spectral output to natural daylight.
If it proves to be useful, here is an article from our website which describes CRI in detail: https://www.waveformlighting.com/high-cri-led
