Skylight's Modification Class entry for the 9th BLF OL contest [pics added]

Currently, I have the flashlight host, the reflector, the leds and the driver PCB on hand. Here are some pictures:

Now I have two Astrolux MF04S flashlights but I bought one of them to use it with the GT94 reflector. This way, I can directly compare the finished modified flashlight with a MF04S. I have been looking for a MF04S host but after they started adding tax a full flashlight didn’t cost much more. Call me crazy for taking apart and modifying a perfectly working MF04S. Crazy

The GT94 reflector fits the MF04S almost perfectly, I will file only a small bit away. Before I bought the second MF04S I already tried it in the first. The order I bought the parts in was first the reflector, then the leds and at last the host. Yes, I know that normally you buy a reflector for a flashlight and not a flashlight for a reflector. Innocent

Of course I will find some good use for the big MF04S reflector. I always wanted to try it with different leds, especially a WhiteFlat 2.

The GT94 reflector looks excellent with the four XHP70.2 leds.

My modified flashlight for this year’s 9th BLF OL contest will be something big. I guess I’m going bigger each year. Cool

What I have on hand is an Astrolux MF04S, a GT94 smooth reflector, a MT09R driver PCB and four XHP70.2. Let’s see how this will turn out. Stay tuned!

Thank you, MascaratumB, the idea came to my mind while I was taking fotos for your recent GAW. Cool

I added pictures in the OP.

What I did so far is taking apart the MF04S, doing a fitment test for the reflector and planning where the leds will sit inside the flashlight.

I am waiting for a few aluminium rods and discs which should arrive in the next few weeks. Until then I will do a few minor preparations and I will start the build when I have the aluminium parts. I will make the spacer out of aluminium, not of copper like in my last two builds, because the MF04S is already heavy enough and I don’t want to hit 2kg.

I misunderstood what you were saying before you added pics. I am planning something different. But your idea looks better. Have fun. Beer

Last week the aluminium parts I have been waiting for arrived. They consist of a 5cm diameter aluminium rod, 10cm diameter 1mm thick and 8cm diameter 3mm thick aluminium plates. I included a measuring tape in the pictures as a size reference.

I found a MT09R driver that I assembled and soldered some time ago.

I filed the lower rim of the reflector a little to make it fit the flashlight better (the upper one of the two cooling rips on the reflector in the picture below).

Here are a few fotos of the parts I will be using.

I expect to really get started with the mod this or next week. I need to take a few beamshots before I disassemble the MF04S.
