Looking for a narrow beam metal reflector (50 mm diameter) for HID bulbs (12 mm

[Mark1982]

Hi,
I'm building a HID diving torch.

I'm going to ultimate the torch, but I've troubles with the reflector...
I've got a wide beam reflector, but I need a narrow one...

So, I'm desperately looking for a metal / aluminium reflector for a 50W HID bulb.


The maximum diameter of the reflector must be 50 mm.

The hole placed at the reflector base (where I will insert the HID bulb) would be 12 mm.

The whole height of the reflector must be less than 39 mm.


The reflector has to produce a narrow beam (8°) and it would try to recover the lost light in order to maximize the narrow beam...

At last, something about the "focus" of the reflector...
I have to put the reflector in contact with the torch glass.
The light source (hid gas ampoule) has to be placed at 20 mm from the glass...
So the reflector mus not be too short in its height, but it have to be a proper height in order to obtain a powerful luminous flux...

Hope You can help me,
regards,
Marco
