Looking for Bright 3W LED Options Over 300 Lumens

Hey, don't forget to share more details about your project! What does this flashlight look like? Knowing any space restrictions or if it needs to be water-resistant can really help others give you better advice. Plus, providing details about your setup can clarify what requirements you're working with. More info could mean better recommendations!

While it's possible to find LEDs that provide decent brightness, typically you might need around 4 to 6 watts for 300 lumens or more. The usual efficiency for LEDs is about 100 lumens per watt, but many newer models can give you over 150 lumens per watt, which could be an option depending on your setup. If you're aiming for that much light at just 3 watts, it will be quite a challenge.

So, here's the thing: your setup with two AA batteries only gives around 8 watt-hours, and they can handle about 2 amps at peak. But if you're looking to use about 1.4 amps, you're probably maxing out the batteries. This means a 300 lumen LED could be pushing your current capacity. You might want to look into either using multiple LEDs or a different power source if brightness is your top priority. But I hear there are LEDs that push 200 lumens per watt, so don't lose hope!
