What to Avoid as a Beginner
Unknown brands with unverified claims. The consumer RLT market is full of low-quality devices with inflated irradiance specifications. 73% of budget panels tested by independent reviewers (GembaRed, 2023) failed to meet their own specifications. Start with a brand that publishes third-party verified data — PlatinumLED, Joovv, and Omnilux are the clearest examples.
Devices with no published wavelength verification. Many brands claim to emit 660nm and 850nm but independent testing has found devices emitting 15nm or more outside their stated wavelengths. Wavelength accuracy matters for aligning with research protocols.
Treatment area vs irradiance confusion. Some manufacturers express power in watts (total output from the panel) rather than mW/cm² at treatment distance. Total watts does not tell you how much light reaches the skin — only irradiance at the treatment distance does.
Building a Practice
Start with one device that covers your primary use case. For most beginners, the PlatinumLED BioMax 600 covers the full spectrum at a practical mid-size. Once you have established a consistent practice and understand which muscle groups or skin areas you are treating, expanding with a face mask (Omnilux) or stepping up to the BioMax 900 is logical.
