The Convoy S2+ Blue is a compact, customizable 18650 LED flashlight for everyday carry (EDC), practical work, camping, and general outdoor use. Its blue aluminum-alloy body, tail switch, and broad selection of LEDs and drivers make it a versatile choice for enthusiasts who want to choose their own beam and operating modes.

Choose the Right S2+ Configuration

This listing lets you build a complete flashlight using three connected options. Choose your LED Type first, then select a compatible Color Temperature & Light Color, followed by the Driver Type. Only combinations offered for this specific body color are selectable.

• LED Type: Options may include Nichia 519A, SST20, SFT40, XPL HI, Osram/Luminus, and others shown in the selector. Different LEDs emphasize different balances of tint, color rendering, brightness, and beam concentration.
• Color Temperature & Light Color: Select the available warm, neutral, or cool-white CCT—or a specialty light color when offered for your chosen LED. Warm white can be comfortable outdoors; neutral white is a versatile everyday choice; cool white may be preferred when maximum perceived brightness is the priority.
• Driver Type: Select a compatible driver and user-interface configuration. Output behavior, efficiency, heat, brightness levels, and mode groups depend on the driver chosen.

Tip: If you prioritize natural-looking colors, consider an LED option explicitly designated as high CRI. If you want a more concentrated beam, compare the available emitter choices; actual beam characteristics depend on the complete LED-and-optics configuration.

Key Features & Specifications

• Model: Convoy S2+ Blue, complete LED flashlight
• Body: Blue aluminum-alloy finish
• Lens: AR-coated glass
• Reflector: Smooth or orange-peel type depending on LED configuration
• Switch: Tail switch; tail-standing capable
• Power: One unprotected flat-top 18650 Li-ion battery (3.6V/3.7V nominal), sold separately

Driver Modes & Operation

Mode behavior is not identical across all variants. For example, the manufacturer's 4-mode interface uses 0.1% → 3% → 30% → 100%, while compatible 12-group drivers allow users to select from multiple brightness/mode groups. Some configurations offer mode memory; follow the instructions for your selected driver rather than assuming every variant uses the same UI.

For high-output versions, the body can become hot during extended use at high brightness. Select an appropriate brightness level and follow normal lithium-ion battery safety practices.

Battery Compatibility – Read Before Ordering

Requires one unprotected flat-top 18650 Li-ion battery (3.6V/3.7V nominal), sold separately. Protected 18650 cells may be too long to fit correctly. Do not force a battery into the tube. Use a quality battery suitable for the current demand of your selected driver, and charge it with a compatible external Li-ion charger. Battery and charger are not included.

Which Version Should You Choose?

• Everyday carry and general utility: Choose a neutral-white LED and a driver with the mode interface you prefer.
• Color-sensitive tasks: Look for a high-CRI LED option and a color temperature suited to your environment.
• More focused outdoor illumination: Compare throw-oriented LED choices and the compatible optics; this compact S2+ is not a substitute for a dedicated long-range searchlight.
• Simple operation: Choose a compatible 4-mode driver if you prefer fewer brightness steps; select a 12-group driver if you want more mode-group flexibility.

Frequently Asked Questions

Does the Convoy S2+ Blue include a battery?
No. One unprotected flat-top 18650 Li-ion battery and a compatible charger must be purchased separately.

Can I use a protected or button-top 18650 cell?
This listing recommends an unprotected flat-top 18650 cell. Protected cells can be too long; do not force incompatible batteries into the flashlight.

Do all LED choices have the same brightness and runtime?
No. Output, beam pattern, power draw, heat, and runtime depend on the exact LED, driver, and battery selected. No single lumen or runtime specification applies to every configuration.

Does every version offer 12 mode groups?
No. The operating interface depends on the driver variant selected in the menu.

Can I choose a different body color?
Use the Body Color selector on the product page to explore available S2+ colors. Some LEDs or drivers may not be offered for every body color.

Please confirm all three dropdown selections before adding to cart. The selected variant determines your LED, light color/CCT, driver, and final price.
