depends on your interests
here is one of my aaa mods to high cri w TiR
some mods are simple LED swaps
some involve driver swaps
some people like 18650 batteries
some like aaa
a few people have access to a lathe, and make their own hosts
others shop convoy, for inexpensive options…
some like single LED lights
some like multi LED lights
if you want to experience a High output Triple available for cheap, you could buy this used FW3a. as a benchmark
