Quoted from ibis:
Im redoing a Meteor and have some of these for the PF but thinking I may change out the back-box lights too. What would be the best one for illuminating the BG without looking like a super bright, out of place LED?
What I do on my backboxes is only place about 1/3 of the LEDs in strategic positions. In other words, I leave 2/3's of the sockets empty. I used to be able to find some really dim LED for dirt cheap, but those are hard to find in the warm white flavor these days. Since then I've found placing 1/3 bulbs then cutting out small squares of black electrical tape and placing them on the tips of the brighter LED's tends to disperse the light outward nicely overall. If you place them in the right spots (behind a face or some roaring tiger, things like that) you can create this nice effect of highlighting the better aspects of a back glass. Also in some spots I will throw in a colored bulb to tone down the brightness some and for added coloring effect on things like lettering. This has an added side effect of really knocking down the amount of glare you get on the PF glass due to an overly bright back box. You can SEE the playfield better, especially at the top.
Here is a prime example of one of my machines with toned down light. Notice how well you can see the playfield even with the PF glass in place-
