Firefly L50 Sol
Firefly L50 Sol
I have a soft spot for tech that nods to older, more nostalgic gear. Restomods, cassette-tech throwbacks, all of it. The L50 Sol hits that sweet spot. In Astral aluminum, it reminds me of the shiny aluminum flashlight that lived in my grandfather’s wood shop. To keep the nostalgia going, I picked a warm tint emitter to mimic the incandescent bulbs of yore. A right angle light with a retro look that doubles as a headlamp? I had to have one.
Full disclosure here at the top. FFL sent me this in exchange for my honest opinion. And that’s what this is. Let’s get into it.
What’s in the box?
Firefly L50 Sol
Lanyard
Spare O-rings
Pocket clip
Lanyard ring
User manual
Headband
It all arrives in a neat little hard plastic box. That’s a big step up from the paper boxes, and I’d bet it helps these lights survive shipping.
Note: the 18650 cell is not included unless you add it at purchase.
Build quality
This is my third Firefly, and the quality still blows me away. You really have to hold one to appreciate it. The head threads on and off smoothly, and so does the tail cap when you swap between the lanyard ring and the pocket clip ring. The tail magnet is strong, the knurling is exquisite, and the switch has a satisfying audible click with great tactile feedback. The pocket clip is sturdy and lets the light sit low in the pocket. Nothing about the build feels like a compromise.
Design
This is where the L50 Sol takes the cake. The Astral aluminum recalls the old aluminum lights of the 70s, and I love it. The knurling and cutouts catch the eye from every angle, and the light looks amazing in direct sun. The RGB aux LEDs glow beautifully behind the beaded TIR, and the lit switch is a nice touch. The angled switch behind the lens puts your thumb right where it wants to rest.
The one downside is that there’s no onboard charging. You have to pull the cell and charge it in an external charger, or in a light that supports onboard charging. It doesn’t bother me, but you should know going in.
UI
The L50 Sol runs the open source Anduril 2. If you’re new to it, it can look intimidating. Give it a little practice and you’ll be navigating the flow chart with ease. It’s worth the effort, because it unlocks a huge amount of customization.
Usability
As an EDC, this light excels. The right angle, warm emitter, and strong tail magnet make it a great companion for work and around the house. It’s bright enough to scan my yard at night, and it’s my go-to “checking under the sink” light. The headband adds a whole new layer. It’s comfortable, easy to adjust, and the rubber rings hold the light steady at whatever angle you set. It’s like getting two lights in one.
Performance
I chose the FFL5009R emitter (2700K, CRI 95, 1800 lumens, 120 meters). It’s warm, easy on the eyes, and plenty bright. With the beaded TIR lens, it easily fills my entire backyard or whatever room I’m in. Smooth or stepped ramping makes it simple to dial in the right brightness for the job.
Summary
I love this thing. The nostalgia and build quality are top notch, the UI is a proven favorite with tons of capability, and it works great as both a headlamp and a pocket EDC. The styling and aux LEDs also get a “wow” from non-enthusiast family and friends when I hand it over. It quickly became one of my favorites in the collection.
