Hello,
I am the guy who designed LED OCD. I just ran across this thread, and despite my first post to the forum bumping an old topic, I just wanted to make a few comments. Sorry if it's considered bad form.
I agree if you want the look of incandescents, you should use incandescents. I have incandescents in both my LOTR and TZ for that very reason.
I designed and use LED OCD for games where I wanted better color (blue that isn't green, etc) or whiter whites. When I put LEDs in a couple of my games, I hated them, and ended up pulling them all back out. Eventually, I decided to do something about it.
The reason B/W games are more "seizure inducing" than Stern games is that the B/W games scan the lamp matrix at 62.5 Hz, while the Stern games do so at 125 Hz. The frequency at which the human eye starts to see the flicker varies from person to person, but 60 Hz is right on the edge. Stern didn't do everything right, though, as their dimming effects work by alternating the lamps during their timeslots, effectively reducing their refresh rate. That's why most of Stern's attract modes with dimming effects look like garbage with LEDs.
With regards to the price of LED OCD. I'd love to be able to make them available for less, but what Menace said is dead on. The cost of the parts, PCB assembly, etc. is well more than half of the $150 USD, and I'm still assembling the cables by hand. Yes, I'm making some money on them, but when I figure in the amount of time I've put into it, I'm making far less than minimum wage.
To the guys who I recognize that have purchased, thank you.
