Run #2 Preorder is CLOSED

The HDSRB Project started when I realized that for many of us, HDS Systems flashlights are our favorite and most reliable lights. A community poll showed that most HDS owners actually own more than one HDS light. I became interested in increasing the versatility of these lights.

The idea is to create a part to your existing ACME threaded HDS light by replacing the existing reflector and bezel to increase throw and add functionality to the light you already own. The LED and beloved driver/UI will remained unchanged, and the design is intended to follow HDS philosophies of Robust Durability and Reliability.

The HDSRB is proudly Made in the USA with Made in the USA raw materials.  . 

Overall design language is kept consistent with HDS aesthetics. You can see the recognizable stainless steel bezel for impact resistance and to protect the lens. Crenelations are consistent with HDS' style, and even the angle flare of the head is consistent with the angle Henry used in the battery tube flare. 

What you'll be receiving:

  • 1 x HDSRB stainless steel bezel
  • 1 x HDSRB reflector housing
  • 1 x HDSRB Custom reflector
  • 1 x UCL Lens
  • 4 x O-rings (installed)

Flashlight not included


Reflector Housing: 6061-T9 Type III anodized aluminum

Bezel: 304 (18-8) stainless steel

Reflector: Electroformed Nickel with aluminum quartz overcoat

Lens: UCL™ Float Glass with broadband AR coating on both sides, >98% transmission 

O-rings: Buna-n



SMO or OP? SMO Reflector
How much does it improve the throw? It depends on the LED. The 5000k 219c I tested on practically doubled the candela, or 50% more throw.

Can I use a clip under it like I do with my other rotary bezel? The clip fits. Depending on the LED the beam may be affected, the 219c I tested grew a couple more rings in the beam while a modded one I have (I think XML-2) was not affected.


How to get yours :

In accordance with Paypal terms regarding pre-orders, you are purchasing a gift card to reserve your HDSRB.


Once machining is complete I will invoice everyone for the balance +SH. You'll enter your gift card code to apply the credit and pay the balance and the reflectors will be put into production. Doing it like this mitigates the chances of me holding on to everyone's funds in the event of machining delays.
Lead time: Due to my experience with the previous run I'm super hesitant to provide a lead time, which is why I'm only asking for a 25% deposit. I do have to establish expectations, so I'm estimating everything should be completed by the end of August. I'm hoping for sooner, but keep in mind this is about half the time the first run took. Consider it an estimation, not a commitment. Once all the machining is complete you'll be notified and we'll put the reflectors into production.

Deposit and prepayment funds are nonrefundable, as the moneys collected will be used to manufacture the custom reflectors and components.

The HDSRB in the pictures is a prototype. Final product may vary slightly.

Perfect addition

I was lucky enough to get one from the previous run. I should have bought 2 more. The quality of the work is no less than perfect, just as HDS is. It makes a super hot spot and throw is phenomenal now. Don’t hesitate to get one and let’s all hope there are many more runs after this one. 


At least one HDSRB reached Germany! After a longer stay @customs die to Corona I picked the parcel up today. I mounted it on a NB40 HDS. The much more focused beam is quite impressive. Great product...

Pictures will come later. It is almost evening here.


Wow, amazing craftsmanship on this thing. I Am more than impressed, and could not be any happier. Thank you so much, Ozythemandias!


Wow this is such a nice aftermarket upgrade! Beautiful fit and finish, totally HDS aesthetics, and perfectly proportioned for the 18650 tube. Beam looks kinda similar to the Makai.

Thanks Ozy!
