Comet is my go to for LEDs, although I strongly support Titan for all my rings. The Comet product line beyond just playfield bulbs is great, and I use their Matrix products with all the mods I make and sell. It seems I am counter to may others here, but my preference is cool white for my GI (frosted domes), and for inserts I prefer the 4 SMD non-domed bulbs for their brightness (I also use the flex 1 and 2 SMD versions where needed). For some colors I do color match inserts (reds, greens, dark blues), for others I use cool white (clears, yellows, cyans), and for others I use warm white (ambers, oranges). For backbox I also tend to like the 4 SMD non domed, but they are bright (nothing wrong with frosted domes in the backbox), and I do tastefully color some of these with white still being the dominant color.

Finally, I love Comet’s 18 SMD flashers. They shock the senses when they fire, and I have a mix of colors in games based upon the coloring of surrounding artwork. Others will prefer white only, and much dimmer flashers.

In the end, I highly suggest you order an assortment of colors and types from Comet to see what you prefer. You probably wouldn’t need to spend more than $20 or so to get a good sampling. Oh, I also ALWAYS order the non-ghosting version of the bulbs for GI and inserts. While it might not be necessary in some games, I figure why take the risk. When I bought my JP it had all Cointaker bulbs in it. Many were dim, but the insert ghosting drove me nuts. I replaced everything with new Comet non-ghosting bulbs, and now all is right with the world again.

I should also say that beyond their products, both Comet and Titan have excellent customer support. The people that run and work for these companies have a true passion for pinball. They treat others like they themselves would want to be treated, are responsive to issues and communicate well, and overall are positive and friendly people.
