Kala Red Light Mini 2.0

Kala positions the Mini 2.0 as the first handheld with four wavelengths, pairing 630 nm and 660 nm red with 830 nm and 850 nm near-infrared across 48 LEDs. Two preset modes split the spectrum — Mode 1 runs 660 + 850 nm and Mode 2 runs 630 + 830 nm — so users can alternate between the shallower and deeper-penetrating pairs. The 546-gram aluminum body, adjustable session timers, and included goggles round out a package clearly aimed at travel bags and gym kits rather than a fixed treatment station.

The spec sheet is complete by handheld standards — 102 × 146 × 35 mm, a 7.4 V / 4,000 mAh lithium battery, 100–240 V charging input, and a two-year warranty — but the irradiance figure of 100 mW/cm² is stated at the surface of the LED, a measurement convention that flatters every device that uses it. On Kala's US storefront the base unit sells for $339.99 against a $399.99 list price, with a stand bundle at $439.99. As a targeted device it covers one joint or facial zone at a time, which is exactly what it is designed for and exactly its limit.
