Equivalents of LED luminaires

[Wiloinge]

I have a question, considering that the current trend is to change HPS, fluorescent luminaires to LED, is there a table that indicates the equivalence between luminaires of different technology?

Lumens are lumens, no matter the source. The real answer is that if you want to know what illuminance, uniformity, ect. you will achieve with the new lighting design, you should be doing a lighting calculation. Historically, most spaces were overlit and LED luminaires have a much greater selection of outputs and much better distribution control than most other sources.

We are upgrading the lights in our library and I am getting rid of half of the fixtures because they over illuminated so much. Of course about half the fixtures were burned out before they even complained about the lighting.
