18650 format is not too bad to sort out.
If you place an order for a McGizmo, you need to identify:
1. The head
2. The LED
3. The light engine
4. The battery pack
So 18650 limits those selections a bit compared to the E-Series compatible lights.
1. Head options are
- "Ram" or "Mule"
- The Ram has a reflector, the Mule does not. So, Ram if you like some throw, Mule if you are happy with pure flood.
2. LED
- This is a tough one … need to pick between current offerings - XM-L2, XP-G2, Nichia 119V, etc. It seems that Don's intention was XM-L2 for those who favor flood, Nichia for those who favor color rendering, XP-G2 to give you a bit more throw. Again, everyone struggles with this one.
3. Light engine
- Easy… the HIVE is the only option on 18650 lights.
4. Battery Pak
- again, fairly easy, as options are limited by 18650. The "Aqua" came out first. It is a twisty, and designed to be a waterproof dive light. By popular demand, Don offered a "Terra", which is a Clicky and lacks the water proofing.
So a twisty based flood light with XM-L2 is ordered as:
AquaMule HIVE XM-L2
A Clicky based reflector light with XP-G2 is ordered as:
TerraRam HIVE XP-G2.
Again, the "HIVE" portion is not really necessary, but it will help you with all future orders if you can wrap your head around picking:
1. Head
2. LED
3. Light Engine
4. Battery Pack
Good Luck!
