Hi
Knna,
Here are three SPD graph from the manufacturers and the bulb properties, if you could please give us a tutorial as how do we now convert the Graph into meaningful data to get the SPD values ?
OSRAM 865 LUMILUX

So 3 Different types of Graph, and how do we now calculate the SDP Values from each of these ?
A small short tutorial will help all of us a lot ?
