Fwiw, instead of tea lights, consider looking at these: https://www.amazon.com/dp/B0BVPQL75F They’re $1.10 vs the .25¢ of a team light, but they are hands down the brightest light of that size class of light, which really does make a difference for explosions. They’re what we use for the lion’s share of smaller fires and explosions we sell online, and they’ve been rock solid quality wise (compared to a lot of other small LEDs). We tested about 2 dozen small LED makes and models and they’re our favorites. We also love the round “balloon lights” sourced by OP. Different reasons than the other light, but also a staple. Worth looking at!
