Most LED props are single-use: a whip is a whip, a staff is a staff, and when you want a new effect you buy a new device. The RGB Critter BT was built the opposite way. It is one app-controlled, color-changing light with a threaded lens that accepts more than 200 twist-on accessories, so a single purchase becomes your whole light painting and flow-arts kit and keeps growing with you. This guide explains how the platform fits together.
The Idea: One Light, Many Tools
At the center is the Critter itself: a bright, rechargeable LED light whose color, brightness, and patterns you set from the free companion app. Everything else twists onto it. Instead of a drawer full of one-trick props, you own one light and a set of inexpensive attachments, and you reconfigure it for whatever you are shooting or performing.
What the Critter Becomes
- A light painting flashlight. On its own it draws orbs, trails, and light writing. See the tutorials and our pick of the best light painting flashlights.
- Shapes and texture. Twist on a light painting blade to add crisp geometry, or a tube or saber for soft, wide, diffused trails.
- A staff. Join two Critters with a Critter Connector and saber tubes to build an LED staff for two-handed spinning.
- A double-sided prop. The same connector makes a double-sided Critter for symmetrical, dual-hand flow.
- Part of the fiber family. The BitWhip fiber optic whip and the fiber optic costume run on the same LED system, so your colors stay matched across every piece.
Why a Platform Beats Single-Use 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.
Who It Is For
- Light painters and photographers: swap blades, tubes, and colors to build complex long-exposure images from one light. Start with the light painting photography guide.
- Flow artists and performers: move the same lights between whip, staff, and double-sided rigs for a coordinated show.
- Beginners: buy the light, learn the basics, and expand only when you are ready. See flow tools for beginners.
- Existing customers: the accessory you buy next always works with the Critter you already own.
Start With the Light

FAQ: The RGB Critter BT Platform
What makes the RGB Critter BT a platform rather than just a flashlight?
Its threaded lens accepts more than 200 twist-on accessories (blades, tubes, sabers, connectors, mounts), so one app-controlled light reconfigures into many different tools.
Do I need to buy everything at once?
No. Start with the light and add accessories over time. Each one works with the Critter you already own.
Does one app control all of it?
Yes. The free companion app sets color, brightness, and patterns for the Critter and the props built on it.
Can I build a staff or double-sided prop myself?
Yes, with two Critters and a Critter Connector. See the LED staff and double-sided Critter guides.
