@Lux-perpetua and Jos, why did you need to take out the driver? Just to see if it is possible? (I admit that i prefer the Q8 with the screwed down driver.)
The most logic explanation for me was to take out the MCPCB and reflow some emitters of your choice.
Emitters can only be exchanged by pulling out the driver from the SP36. I wanted to have a SP36 with 4x LH351D 5.000K 70CRI. Again, there is no reason to use glue in this flashlight, at least not such extreme amounts. The driver remains at its place even without glue.
You may be lucky to catch a sample with less glue than mine was. A friend of mine opened two of the SP36. The second one had two small blobs of glue only, reducing the effort significantly to pull the driver.
