        oh - I'd change the decay and falloff to Inverse Square & Smooth Cubic, respectively. Is physical camera turned on or off?

            Those changes produce basically black results...(same intensity - 20)

              Yes, yes they would. The physical camera settings are the default for a brightly lit outdoor scene. Try changing the camera settings to shutter speed 30, f number 4.0, and film speed 400. That's just a quick guess, but you can adjust those values as needed to get the right amount of exposure in the scene.

                Here are the results with those last suggested settings.

                  I'll keep adjusting until i am doing this the right way with the right settings but in the interim, for this current project which i am trying to finish within the hour πŸ˜„ - why does this happen (attached)?

                  The slightest change in color or multiplier (value of 1) turns the color white. I know I have had previous projects where the value was 30 or even 100 and had a perfect glow to it and maintained its color, didnt change to pink or white... something must be different that I am not noticing.

                    Look... it reflects the correct color and intensity but no matter what i try, it emits the bright white 😍

                      sorry - I don't usually use scalar for my units. I typically use luminous power. For the camera settings I gave you, you can use 10000 for the spotlight power. Then for a purple emmissive material, you can use an intensity of about 0.5 The brighter the intensity, the more pink it will look. May need to set the shutter slower, like 15

                      Also, try adding a radius of 3.0 to your spotlight for softer shadows, and increase the subdivs for the spotlights to something like 16 or 24.

                      Hope that helps.

                          I took a stab at some settings since I am working on a similar sort of setup (spotlights on an object) and looked at what values would work for the lighting and material. Here is what I've got.

                            closer but still very white.

                            let me check out your settings.

                                i got frustrated and slammed the shutter speed up to 200 just to see what would happen and it actually came closer to my desired results. The problems now are there is less glow and I am guessing I will need a ton of spot lights to illuminate the scene now since it appears so dim. SO weird.

                                  I think you just need to keep reducing the multiplier on the emmissive layer. It also helps to change the emmissive color to lower saturation and make it a darker value.
