Quote from that X70 Review
"The following runtime was done, using the fan on its highest setting. This resulted in a completely different runtime graph. Although the output drop looks the same, the average output of its battery life was about 3 times brighter. The output is still about 20,000 lumens for 30 minutes. There are a few ups-and-down in the graph. This is probably the thermal heat configuration of the driver. The fan does a good job keeping the head cool! "
Looking back over the data again and how much improvement that handle seems to make according to both these sources, if a manufacturer took the time to make a very robust handle mounted similar to what is on the Xeray/Lemax lights, and made the mounting point much larger and stronger, combine that taking notes from top PC fan manufacturers and make a larger and more efficient fan, and some changes to the heat fins and how the air circulates, I see no reason why this couldn't be used as a low cost cooling solution compared to the more complex and expensive solution Imalent uses. There is no requirement to have a radical design approach that must be made from the ground up, it's a quick, effective fix. That is of course provided that these future models show favorable data, like what has been shown for Acebeam solution. Unfortunately, the Imalents fans automatically engage, so it's not possible to do a test and see what the difference in performance is compared to the "Mickey Mouse" solution.
More of these actively cooled lights will continue to appear on the market, it will be interesting to see what direction they go. I made a thread earlier this year discussing Liquid Cooling in LED lights. It's been done, and is highly effective.
