Yeah, as a summary for the Wizard Pro the pre-production sample had a very high thermal protection 'critical' threshold at just over 80 celsius. They seem to have severely reduced the threshold to 65 celsius on the production model. However, there are different stages of coloured warning lights behind the button which on the pre-production flash green at 65, yellow at 70, orange at 75 and red at 80 (or something like that), but they forgot to update the temperatures at which these flash for the production model. So you end up missing out entirely on the colour warning LEDs as it steps down as soon as it gets to 65 now.
Also, 65 may be a bit too low anyway as in a warm room and no airflow it will step down to 100 lumens after only about 3-5 minutes. Outside 15 celsius and walking pace it won't step down, but stand still for a few minutes and it will.
On the H602 I'd prefer some sort of infinitely variable stepdown which maintains the max possible safe output in whatever environment. I find it hard to believe that the H602 could have better physical thermal properties however as Zebralight tend to go for as small as possible leaving little thermal mass.
