Forge 66
Forge 66 is a hand-built high-output flashlight kit with active cooling, a wide flood beam, and long-throw reach up to 870 meters. It is built around a constant 65W / 7,000 lm high-output mode, approximately 190,000 cd beam intensity, and 45W Type-C charge and discharge support.
- 65W / 7,000 lm mode: constant output with active cooling
- Beam: wide flood plus long throw up to 870 meters
- Beam intensity: approximately 190,000 cd
- USB-C power: 45W charge and discharge
- Full charge: about 1 hour
- Runtime: about 24 minutes at 65W, 54 minutes at 30W, and 8 hours at 3W
- Housing: PETG-FG 3D-printed shell set
- Thermal stack: 30 × 30 × 50 mm heatsink with a 3010 cooling fan
- Optics: 50 mm lens with a 5500K LED setup
Battery options
Without Battery (default): No battery pack is included. Forge 66 requires two matched high-discharge 21700 lithium-ion cells configured as a 2S pack (7.2-7.4V nominal / 8.4V fully charged) with a compatible 2S protection board. Use cells with sufficient discharge capability for 65W operation.
With Battery: Includes one compatible two-cell 21700 battery pack.
Forge 66 ships as a parts kit for experienced builders and is not a fully assembled finished flashlight.

Before you order
Forge 66 FAQ
Clear answers about the kit format, batteries, assembly, 45W Type-C power, and the actively cooled 65W output mode. Choose Your Forge 66Is Forge 66 fully assembled?
No. Forge 66 ships as a separated parts kit for final assembly.
Are batteries included?
The default Without Battery option does not include a battery pack. It requires two matched high-discharge 21700 lithium-ion cells configured as a 2S pack (7.2-7.4V nominal / 8.4V fully charged) with a compatible 2S protection board. The With Battery option includes one compatible two-cell battery pack.
Does it require soldering?
No soldering is required for normal final assembly.
What tool do I need?
A screwdriver is required for assembly.
How difficult is the assembly?
The kit is designed for simple final assembly: seat the body parts, fit the front glass, close the rear cap, and tighten the screws.
How does it handle heat at 65W / 7000 lm?
The 65W mode uses a dedicated 30x30x50mm heatsink and a 3010 fan to sustain output without step-down under normal use while keeping the handle comfortable to hold.
Can it charge over USB-C?
Yes. Forge 66 supports 45W Type-C charging and discharging, with about one hour required for a full charge.
Who is this kit for?
Forge 66 is best for experienced builders who are comfortable assembling and maintaining high-output hardware.

Performance proof
Active cooling sustains the high-output mode without automatic step-down under normal use while keeping the handle comfortable.
Runtime targets for 65W, 30W, and 3W modes give buyers a clear power budget.
Type-C charging and discharge support a compact power workflow with about one hour to full charge.
High beam intensity supports the combined broad flood and long-range beam profile.
Specification-backed claims
Performance messaging is tied to concrete build parameters: board thickness, charge IC, battery format, protection board, cooling package, and runtime by power mode.
