The TR4 makes professional-level teeth whitening achievable at home. Apply, activate, and let the dual LED technology do the work โ just 16 minutes per session is all it takes.



The TR4 doesn't rely on a single light source. Its 32 LEDs combine two distinct wavelengths โ each playing a specific, complementary role in your whitening treatment.

The TR4 includes three 3ml whitening gel syringes formulated with PAP+ โ a modern, science-backed alternative to traditional hydrogen peroxide whitening systems. PAP+ (Phthalimido Peroxy Caproic Acid) oxidises stain molecules directly within the tooth structure, lifting discolouration from coffee, tea, wine and smoking without the enamel erosion or gum sensitivity commonly associated with peroxide-based treatments. The result is visible brightening with each session and a progressively whiter smile that you can maintain comfortably at home.

The TR4's wireless, rechargeable design eliminates the inconvenience of tethered whitening devices. The 450mAh lithium battery delivers more than ten full 16-minute sessions from a single charge, rechargeable in around 100 minutes via USB magnetic connection. At just 43 grams and measuring 83.5 ร 66 ร 26mm, it's compact enough to pack without a second thought. The IPX6 waterproof rating means it handles accidental splashes in the bathroom without concern, and its lightweight ergonomic mouth tray ensures even gel coverage for consistently uniform whitening results.

The TR4's touch control interface makes operation completely intuitive. A sensitive touch-and-long-press system activates your session instantly, while the automatic 16-minute cycle handles the timing so you can multitask freely โ read, watch, relax. Buzzer alerts notify you at session start, completion, and when the battery is running low, so you're never caught off guard. The uniform tray design ensures full coverage across all visible teeth, delivering balanced whitening results without patchy inconsistency.

The Trendlox TR4 Rechargeable LED Teeth Whitening Kit is a complete, professional-inspired whitening system designed for effective, sensitivity-free use at home. At its core is a 32-LED dual-wavelength light engine combining high-brightness blue LEDs โ which activate the PAP+ whitening formula to break down surface and sub-surface staining โ with red LEDs that support gum comfort and tissue balance during each session. This dual-light approach is what distinguishes the TR4 from single-wavelength devices and makes it particularly well-suited to those who have previously found whitening treatments uncomfortable.
The included PAP+ whitening formula is peroxide-free, representing the modern professional standard for sensitivity-conscious whitening. Three 3ml gel syringes are included in the kit, providing everything needed to begin a full course of treatment immediately. PAP+ (Phthalimido Peroxy Caproic Acid) targets discolouration from coffee, tea, wine, food and smoking without the enamel-weakening or gum irritation associated with traditional hydrogen peroxide systems โ producing progressive, visible results with consistent use.
The TR4's wireless, rechargeable design features a 450mAh lithium battery delivering more than ten 16-minute sessions per charge, with USB magnetic charging completing in approximately 100 minutes. Its touch control interface with automatic session timer and buzzer alerts makes operation effortless. Weighing just 43 grams with an IPX6 waterproof rating, it is as practical for daily home use as it is for travel.
