I needed to buy new emergency flashlights, and after a bit of searching I settled on the Streamlight Dualie, a 3AA 140 lumen LED flashlight with separate spotlight and floodlight modes.
I have numerous everyday and regular-use flashlights, but had very different criteria when it came to emergency flashlights.
Part of what prompted this search was a conversation with my parents about how they needed another flashlight or two. After a bit of research, the Dualie seemed perfect.
The Dualie has separate floodlight and spotlight modes. The spotlight is built into the end of the flashlight, and the floodlight is built into the front side.
With the floodlight, you can clip the flashlight to a pocket, or place it standing up face-down to aim it where you please.
The spotlight and floodlight emitters have independent controls, so you can use either, or have them both on at the same.
The operation is simple, with on/off controls and nothing more.
As this is a 3AA flashlight, batteries are readily available.
The spotlight delivers 140 lumens of light, and so does the floodlight. Together, they emit 245 lumens. Runtime on fresh batteries is 18 hours for either mode, or 9 hours together.
- Impact-resistant housing
- Yellow housing stands out (also available in black)
- Easy to change batteries
- Textured grip
- Dual and independently-controlled pushbutton switches
- Large spring-action belt clip
- AA batteries are easy to find
- IP67 dust-tight and waterproof
- 2 meter impact resistance
- Wide operating temperature range (-20 to 130°F)
- Rugged-feeling design
- Chemical-resistant housing
- Intrinsically-safe design
- Streamlight reputation
- Easy controls and operation
- Light weight
- Long runtime
- Medium brightness
- No output mode controls (aside from on/off)
This isn’t a smart flashlight, meaning there are no programmable output modes. I like the simplicity of the on/off controls, but it hampers its versatility and performance as an everyday light. But, I did buy it specifically as an easy-to-grab light that I can pass around to other family members if needed.
$31 seems a bit high for a plastic-bodied on/off 140 lumens flashlight. However, Streamlight has a very good reputation, and I feel this is a flashlight that won’t let me down.
With a 2 meter drop rating and IP67 waterproof rating, the Dualie should be able to endure all kinds of environmental conditions and even incidental rough handling.
I probably won’t use the floodlight emitter mode a lot, but it seems good to have. As it’s on the side of the light, placing the flashlight vertical and face-down creates a stable base to aim it from.
The intrinsically-safe aspect – which usually means it cannot spark an explosion in the presence of combustible gasses – isn’t a feature I sought out, but can’t hurt to have.
Some people will scoff at the 140 lumen rating, but in reality that is plenty of light.
From Streamlight’s performance curve chart, the output brightness tapers away from 140 lumens somewhat quickly, with the 18 hours of runtime based on the amount of time it takes to drop down to 10% of its max output. I figure that 9 hours might be more realistic, after which I would use the half-depleted cells in 1xAA pocket lights or similar.
I will likely replace the included alkaline cells with lithium cells, which have a long shelf life and tend to be higher performing.
Overall, this flashlight checks off all the major boxes – it’s quick to find, easy to use, fairly bright and long-lasting, is powered by easily-replaceable batteries, and feels very durable. I have used enough Streamlight products to trust their quality and reliability.
Some of its aspects make this model a less-than-ideal EDC or daily-use flashlight, but that’s not what I bought them for.
I also wish the price was a bit lower.
I ordered two for my parents and two for my own home, and have zero regrets so far.
My challenge now is in finding a flashlight that’s at least 80% as good for half the price. I am very happy with my choice, but would like to find a more budget-friendly recommendation for others.
