The short answer: the fastest way to glow at Burning Man is a rechargeable fiber optic costume: hundreds of end-glow fiber strands powered by one app-controlled flashlight that clips to your outfit. It survives dust, swaps batteries in seconds, changes to any of 16 million colors from your phone, and leaves zero MOOP behind. We are the Oregon makers of the RGB Critter BT, and this is the honest guide to lighting yourself, your bike, and your camp for Black Rock City.
Burning Man 2026 runs August 30 to September 7 in Black Rock City, Nevada, with the theme Axis Mundi. Nights on the playa are enormous and dark. Light is not decoration out there; it is how you are seen, how your friends find you, and how you avoid getting clipped by a bike at 2 a.m.
Your body: the fiber optic costume
The Fiber Optic Costume Kit (from $179.95) is the core of a playa light costume. You get a bundle of end-glow fibers, either 360 strands at 6 ft or 500 strands in 6, 8, 10, or 12 ft lengths, powered by the RGB Critter BT. Weave the fibers through a coat, dress, wings, an umbrella, or a broom-style staff; the light travels down every strand and glows at the tips.
- Cut to fit. End-glow fiber can be trimmed to any length without losing brightness.
- One light runs it all. The Critter twists off the costume bundle and onto a whip, saber, or diffuser, so one flashlight covers your whole week.
- App or buttons. Set colors and patterns from your phone, or use the three onboard buttons when your phone is buried in a dust bag.

Your bike: Jupiter Rope
Bikes are mandatory transport in Black Rock City, and an unlit bike is both a hazard and a magnet for theft-by-confusion. The Jupiter Rope Kit ($159.95) is a thick, flexible side-glow rope, like EL wire but far brighter, tougher, and capable of any color, that zip-ties along your frame in minutes and runs off the same swappable-battery Critter system.
Your hands: something to play with
Deep playa at night is where flow props shine. The BitWhip (from $149.95) paints ribbons of light you can see from an art car away, and the LED saber kits hold up to actual dueling. If you only bring one prop, bring the whip; it is the most social object we make.
Playa-proofing: dust, batteries, cold
- Dust: the Critter's grippy silicone housing and threaded metal body handle playa dust well. Wipe fibers with a dry cloth; do not use solvents. Full care routine in our care and maintenance guide.
- Batteries: everything runs on swappable 18650 cells with roughly 7 hours of runtime per charge. Bring spares; swap in seconds instead of hunting for a charger mid-burn. USB-C charging works fine off a solar generator or power bank during the day.
- Cold nights: lithium cells drain faster in the cold. Keep your spare battery in an inside pocket, not your bike basket.
- MOOP: rechargeable LED gear beats glow sticks. Nothing to snap, nothing to leak, nothing left on the playa.
When to order
Give yourself slack: order by early August for US delivery with time to test and weave your costume before you pack. International burners should order earlier. Test everything at home first; the playa is a terrible place to learn your gear.
FAQ
How long does a fiber optic costume run on one charge?
Roughly 7 hours per 18650 battery at typical brightness, and batteries swap in seconds. Two spares covers dusk-to-sunrise comfortably.
Can I wash a fiber optic costume?
Remove the fiber bundle and flashlight first. The fibers wipe clean with a dry or slightly damp cloth; wash the garment separately.
Is end-glow or sparkle fiber better for costumes?
End glow gives clean points of light at every tip and is the more durable choice for a week of playa abuse. Sparkle twinkles along each strand but is more fragile. Full breakdown: End Glow vs Sparkle, explained.
Will dust ruin the light?
No. The housing is sealed with O-rings and silicone. Keep the threads clean when swapping accessories and you are fine.
What if something breaks out there?
Everything comes with a 2-year warranty, and a lifetime upgrade is available. Details on our warranty page.
