DTR 20mm Diode Module Host Bundle Summary
The DTR 20mm Diode Module Host bundle includes the following:
• Your choice of black anodized C6 or S4 host (no logo) with DTR 20mm diode module adapter
• Drilled driver pill & brass ring
• Unwired blank battery contact board
• Your choice of standard 3-element or G-2 lens, both with extended focus ring
• Your choice of extended focus ring color
• External lens spring
• Silicone lens cap
• Ceramique thermal compound
NOTE: Does not include diode, diode module or driver circuit.
This host bundle is designed to use a DTR 20mm copper diode module which can be purchased here:DTR Copper Diode ModulesThe inside lip of the adapter makes direct contact with the module and holds it in compression against the driver pill. By using a small amount of thermal grease, effective heat transfer can be established from the module to the adapter and the pill, and through the rest of the host.Clearly a good number of different diode-driver combinations can be used in this configuration. We leave it to the imagination of the builder to decide what is the best combination of parts for their application.An included O-ring can be placed between the end of the module and the inside lip of the module adapter to compensate for slight tolerances in the length of the module if necessary.Note that this product is intended for use with the DTR 20mm aluminum and copper modules with the built-in driver shelf.
20mm DTR build - s4 - Jay - 3/16/2018
Its a nice host. I got a DTR BDR-209 20mm module to use with the s4. Unfortunately this DTR module measures about 23mm in length while the s4 host adaptor has about 31mm length inside; solved this with some cheap washers to space it out (22mm OD, 16mm ID). I'm sure other DTR modules are longer though. You may also save a few bucks if ordering the s4 parts individually (assuming you get a 6 3E lens from DTR). My s4 20mm bundle also did not come with a pill, brass ring, blank contact board, external lens spring, or thermal compound. Oh well; bad luck, I just ordered some more parts instead.. :(
