The 470 isn’t actually 470 though, they are using 462-465nm diodesHonestly, they will all burn. Its all about preference! If you want a crazy powerful boring blue, hit the 7W
If you want a pretty and stunning 5W, Id so go for the 470!!
If you want a bright intense green beam which is probably visible in daylight, hell, get the 1.6W green
Id personally go for that 5W 470nm!!
