Bright but small enough to not encumber the life jacket (or donut throw). This is turned on manually. Have not tested in real life or death situation but I am confirmable with the quality. The one on the donut sits outside all the time and I periodically twist it to make sure it comes on. No failures. Review: Yo compré una unidad para usar como complemento de seguridad de los chalecos salvavidas en mi velero. Mi primera decepción es que esperaba una luz "Strobe", que generalmente se interpreta como destelleante pero no pasa de ser una luz intermitente muy normalita. La segunda decepción es que pensaba usarlo atado al chaleco salvavidas, contando que flotaba, pero al contrario, se hunde por el peso de las pilas, y debajo del agua esa tenue luz es prácticamente inútil. Intentaré darle uso añadiendo a su alrededor un anillo flotador. ## Features - The ACR 3963.1 C-Light is a reliable USCG/SOLAS approved 20 Lumen LED Light with a typical operating life of 30 hours. - Super Bright, 20 Lumen LED Light Waterproof Tested for 24 Hours at 1M - Simple Twist On/Twist Off Activation Requires 2 AA 1.5V Batteries - Continuous Operating Life of 30+ Hours - Small Design fits in pocket or easily attached to a Lifejacket *Replaced ACR 3355 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E7MVEUQ | | ASIN | B01E7MVEUQ | | Amperage | 0.33 Amps | | Are Batteries Included | No | | Brand | acr | | Brightness | 20 Lumen | | Bulb Features | manual activated | | Colour | Yellow | | Country of Origin | USA | | Country of Origin | USA | | Customer Reviews | 4.3 4.3 out of 5 stars (498) | | Date First Available | 13 April 2016 | | Department | horns, Whistles | | Department | horns, Whistles | | Finish Type | Powder Coated | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 17.9 x 17.2 x 6.9 Centimeters | | Item Dimensions LxWxH | 17.9 x 17.2 x 6.9 Centimeters | | Item Weight | 0.28 g | | Item Weight | 0.28 g | | Item model number | 3965.1 | | Item model number | 3965.1 | | Light Output Maximum | 20 Lumens | | Light Source Type | Light Emitting Diode | | Light Source Wattage | 0.7 Watts | | Manufacturer | ACR | | Manufacturer | ACR | | Maximum Compatible Light Source Wattage | 0.7 Watts | | Mounting Type | Clip Mount | | Number of Light Sources | 1 | | Power Source | Battery Powered | | Product Dimensions | 17.91 x 17.22 x 6.86 cm; 0.28 g | | Product Dimensions | 17.91 x 17.22 x 6.86 cm; 0.28 g | | Shade Material | Plastic | | Shape | Rectangular | | Style | Modern | | Voltage | 5 Volts | ## Product Details - **Colour:** Yellow - **Finish Type:** Powder Coated - **Light Source Type:** Light Emitting Diode - **Shade Material:** Plastic - **Shape:** Rectangular ## Images ![C-Strobe™ - Manual Activated LED PFD Emergency Strobe w/Clip - Image 1](https://m.media-amazon.com/images/I/4126NgGJ31L.jpg) ## Questions & Answers **Q: Is anyone using rechargeable batteries with this? How long is it flashing for you then, please? Thank you.** A: Rechargable batteries do not last as long as top quality alkaline's nor do they hold a charge as long. Plus, are you going to remember to recharge them often? Throw some Duracell's in and be done. Lithium if you want some Overkill. If the alkaline's wear out I've been in the water way to long. **Q: Does this meet the uscg 161.013 requirements for nighttime distress signal??** A: It is too small and weak to serve as the vessel nighttime distress light, it is really meant to locate an individual who has fallen overboard at night. **Q: What type of batteries does this strobe require?** A: AA **Q: Visibility range** A: It's about 3 miles. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***K on 9 September 2025* Good product.
