Every RGB Critter Accessory Explained: One Light, Dozens of Tools

The core: the RGB Critter BT

Before the accessories, understand the hub. The RGB Critter BT is a 170-lumen, Bluetooth, app-controlled color-changing flashlight: 16 million colors, 145+ modes, adjustable strobe, unlimited custom playlists through the iOS and Android app, and firmware updates so it keeps improving. It works perfectly well without the app too. On its own it is a flashlight; twisted into anything below, it is the power and the brains of the whole tool. Reviewers ranked it the best RGB color-mixing flashlight for light painting in 2026. Start with our complete RGB Critter BT guide if you are new to it.

Light painting shapers

These are the tools photographers use to draw with light in long exposures. Each one takes the Critter's raw beam and gives it a distinct shape on the sensor.

Light painting blades: crisp edges and clean planes

Our light painting blades are clear 8mm acrylic blades that catch and shape the Critter's light into crisp edges and planes. Sweep one through a long exposure and you get a solid ribbon of color; flick it and you get sharp slashes. Blades are the fastest way to make a single Critter look like a full lighting rig in camera.

Acrylic writers & orb tools: text in the air and perfect orbs

The acrylic writer and orb tools do exactly what their names promise: the writer is shaped for writing legible text and line work in mid-air, and the orb tools are built for spinning perfect light orbs, one of the most recognizable tricks in light painting. Both live in the full light painting tools collection, and both run off the same Critter as everything else on this page.

Fiber optic dusters: soft, feathered, organic texture

Where blades give you hard edges, fiber optic dusters give you the opposite: soft fiber bursts that paint organic, feathered textures. They are the tool for wispy fills, glowing "fur," and dreamy backgrounds behind a subject. The same wearable-fiber idea scales up into the Fiber Optic Costume Kit, which puts glowing fiber on the performer for costumes and portraits.

Light painting tubes: bold geometry and full backdrops

The modular light painting tubes — Rectangle, Circle, Digital Feather, Crown Jewel, and more — are diffusing shapes for bold geometric strokes and wall-of-color backdrops. Because they are modular, the same tubes also assemble into sabers, which is where the photography side of the platform crosses over into the flow side.

Flow arts tools

For spinning, dancing, and performance, the Critter drives a family of motion tools.

BitWhip: the flagship fiber optic whip

The BitWhip is our flagship fiber optic whip, available in 140, 200, and 300 fiber counts and in End Glow or Sparkle finishes — the brightest fiber trails in the lineup. A complete BitWhip is $159.95 for 140 fibers, up to $179.95 for 300; if you already own an RGB Critter BT, the twist-on accessory head is just $29.95–$54.95, because the light you own is the expensive half. The whip itself carries a lifetime warranty, and the light carries 2 years with a lifetime upgrade available (warranty details). For dual-handed, symmetrical spinning there is the Double BitWhip, two whips driven from connected Critters.

Sabers, staffs & rope: smooth, even trails in motion

The Sol Saber is a diffusing tube saber in four patterns (Sol, Honeycomb, Butterfly and Stellar) and six lengths, where the diffusion smooths the Critter's light into clean, even trails. The LED Staff is a full-length contact and spinning staff lit end to end by Critters. And the Jupiter Rope is a flexible rope tool for fluid, rope-dart-style flow. All of them build from the same modular tube system, so parts carry over as your practice grows.

The connective tissue

Adapters, connectors & housings: one light, almost anything

This is where the platform really opens up. A range of adapters and connectors let one Critter, or several linked together, drive almost anything:

• Critter Connectors — join two Critters back to back for double-ended whips, staffs, and contact tools.
• Tube and saber adapters — mount the Critter into modular saber tubes, T8 tubes, and more.
• Crystal holders, nunchuck adapter, sparkler and tripod adapters — purpose-built mounts for specialty effects and rig setups.
• Pro aluminum housings & faceplates — upgrade the Critter's shell in matte black for a premium, durable build.

Because the app can control up to 10 connected units together, multi-Critter builds stay in perfect color sync while you perform or shoot.

Why a platform beats single-use props

Every piece above shares one light, and that is the whole point of buying this way rather than buying a drawer of one-trick props.

• Buy once, grow over time. Start with the bare light, then add an accessory whenever you want a new effect, instead of rebuying a whole prop.
• Matched color everywhere. Because one app controls the whole system, your flashlight, whip, and staff can all share the same palette in a performance.
• Repairable and modular. Parts come apart and swap, so a single damaged piece does not mean a new prop.
• One thing to learn. The controls are the same whether you are holding a flashlight or a staff.
