Like others said, only two types of bulbs - wedge base or bayonet. I would only look at 1smd and 2smd bulbs. I like to use 1smd in inserts and 2smd for gi. Color match inserts except for yellow and orange where warm white looks better. Clear lens for inserts and frosted lens for backbox, gi, or in places that needs light more spread out. I might use a 2smd frosted bulb to light up a larger insert for example. Flex head bulbs good for where light needs to be directed. For gi, the choice is whether to go with warm white (yellowish light similar to incadescents), cool white (more white light), and sunlight (in between warm and cool). Sunlight is my preference. To get started, buy some sample bulbs and try them out to see what looks best to you.
Avoid kits. Some have some interesting use of color to but it nicely. Walk away from the purple bulbs lol. Easiest thing would just be to buy a bunch of warm white frosted bulbs in wedge and bayonet but no fun in that. I make a spreadsheet of all the inserts, backbox bulbs, and gi. For each bulb, I note the bulb type, color, lens type, and count. I also note where I want to add lighting and try to order exactly what I need. It's very time consuming but worth getting it right if you plan on keeping the machine.
I also recommend comet. The owner and past owner are very helpful with questions. Prices are good and they have a huge variety of bulbs. I especially like their Matrix stuff that makes adding lighting super easy.
