One thing i noticed on AE is lots of these flashlights you can get heavily discounted on the super deal section if you're patient. Like they have the TS26s for $25 with battery. I paid around $35 a month ago.
Hello sir. Please read this. Please subscribe to my channel too. 😊🙏 In flashlights, "buck drivers" and "linear drivers" are two types of circuits used to regulate the LED's power, helping to control brightness, runtime, and efficiency. 1. Buck Driver A buck driver is a type of DC-DC converter that steps down the voltage from the battery to a lower, usable level for the LED. It does this by switching on and off rapidly, using inductors, capacitors, and other components to efficiently manage and stabilize current flow. Key points about buck drivers include: Efficiency: Typically very efficient (often 80-90%), meaning less energy is wasted as heat. Battery Compatibility: Works well with high-voltage batteries (e.g., Li-ion batteries) and can handle a wide range of input voltages. Brightness Regulation: Can maintain consistent brightness as the battery voltage drops. Cost & Complexity: Generally more complex and costly due to additional components. Use Case: Suitable for high-power flashlights where efficiency and consistent brightness are essential. 2. Linear Driver A linear driver, on the other hand, is simpler and less efficient than a buck driver. It controls current by dissipating excess voltage as heat, similar to a resistor. This design has certain limitations but is easier and cheaper to produce. Efficiency: Lower efficiency because it simply "burns off" excess power, especially when input voltage is much higher than the LED’s voltage requirement. Battery Compatibility: Works best with batteries that provide voltage close to the LED’s forward voltage (like NiMH or lower-voltage Li-ion cells). Brightness Regulation: Brightness can drop noticeably as battery voltage decreases since there’s no active control to boost or buck voltage. Cost & Complexity: Simple and cost-effective, often used in budget flashlights. Use Case: Suitable for lower-cost or budget flashlights where simplicity and cost matter more than efficiency. Summary Buck Driver: Efficient, maintains brightness better, handles higher voltages well, but is complex and costlier. Linear Driver: Simple, cheaper, but less efficient and doesn't handle higher input voltages as well.
Can you recommend me a sucsessor to my Sofirn C8F? I need: - Turbo 3000lm - stable 1200lm for about 1-2h - not tactical, needs enough flood - USB-C charging port on the flashlight
Hello sir. Wurkkos TS22, TS26S, Sofirn sc33s sir. You can check 1lumen for runtime graph of these flashlights. Thanks for watching and your support sir 😊. Please subscribe 🙏.
Hello sir. Very difficult question. Personally I like bloody beam sir. There are many models that I like such as Convoy Sofirn Wurkkos. They are good budget flashlights. Thanks for watching and your support sir. Please subscribe 😊🙏.
Hello sir. They're quite different sir. Sc31pro is more powerful with Anduril. FC11C has simpler ui and great tint. If you don't like Anduril, FC11C sir. Thank you very much for your support sir 😊. Please subscribe 🙏.
Before watching Weerapat's video: I don't need another flashlight. 😐🔦🚫
After watching: I want that FC11C too! 😨 🔦☑
Hello sir. Hahaha. Thanks for watching and your support sir 😊🙏.

Hello sir. Yes. Just wait and you can save money. Thanks for watching and your support sir 😊🙏.
Nice flashlight. Recently acquired. Importantly, he is a buck driver.
Hello sir. I can't agree more. Thanks for watching and your support sir 😊. Please subscribe 🙏.
@@weerapatkiatdumrongMeanwhile, Wuben is raising money on Kickstarter for the wuben x2 pro flashlight lol.
I am looking forward to get mine 😁🙏
Hello sir. Great sir. Thanks for watching and your support sir 😊. Please subscribe 🙏.
The review is wonderful (as always). What does buck driver mean? Thank you!

@@weerapatkiatdumrongThanks a lot for detailed info!
Convoy S21B or wurkkos FC11C if same 519A emitter which one worth to buy sir?
hello sir, does this flashlight get a little brighter with a battery like vtc5 or Samsung 30q?
Hello sir. That might be possible sir. Thanks for watching and your support sir. Please subscribe 😊🙏.

@@weerapatkiatdumrong wow the sp33s looks very good
😮Wow ‼️🫰😄😸🐾🎉🎊🎉🎊 Very nice 👉🔦‼️👍😄😸🐾
Thanks 🙏‼️
Thanks for watching and your support sir 😊. Please subscribe 🙏.
The flash light you use is 5000k or 6000k??
Hello sir. 5000k sir. Thanks for watching and your support sir 😊. Please subscribe 🙏
What are your top 3 models you like most
Hello sir. Very difficult question. Personally I like bloody beam sir. There are many models that I like such as Convoy Sofirn Wurkkos. They are good budget flashlights. Thanks for watching and your support sir. Please subscribe 😊🙏.
I bought wurkkos ts26s after I read your review about it.
I’m waiting for it
Which is better sc31 pro vs fc11c?
Hello sir. They're quite different sir. Sc31pro is more powerful with Anduril. FC11C has simpler ui and great tint. If you don't like Anduril, FC11C sir. Thank you very much for your support sir 😊. Please subscribe 🙏.
