Seems like a very cool product. I'll probably put a warm white order in once you get them back in stock.

Will the ones with built-in resistors still work with games with the modified-for-led lamp boards or replacement lamp boards?

I've got an LED'ed Paragon with a resistor-modified lamp board so I wouldn't need the ones with a built-in resistor. But a lot of my repair calls are for Ballys with original lamp boards. So it'd be nice to have a stock on hand of the resistor ones. And if they're safe to use for both types of games, that would be ideal.

So I'm converting a client's Harlem Globetrotters to LEDs, and these are awesome! So user friendly. I'm wondering if there is a solution to prevent strobing for GI applications? I've used LEDs in GI for other games and didn't notice the strobing that I see. Is it a Bally thing?

Well, there are some places on Harlem where GI bulbs don't really stick up through the PF, and instead are mounted like insert lights underneath. But Yopp gave me my answer anyway. So no dice.
