Any opinions on these? I know ghosting and strobing are issues for inserts, but these would be for playfield and backbox GI only. They're so cheap at $.39/ea that I'm thinking about a mix of frosted tip ones (if the bulb is visible) and the concave (if under plastic). No particular need or anything, but I'm going to place an order with PBL anyway so thought I might test a few LEDs.
