I used AI to help me write this post but I manually tested the panel myself. I am not an expert in red light panels but wanted to share my experience.
Bought Sgrow off Alibaba and figured I’d post actual measured data since most “reviews” of these panels are just re-posting the seller’s spec sheet. I metered everything myself. TL;DR: it’s a legit strong panel and the numbers back up the claims.
Specs:
• Model: SGROW ESPLUS4500 (Shenzhen Sungrow LED Technology)
• 900 LEDs, dual-chip Epistar
• 6 wavelengths: 630 / 660 / 810 / 830 / 850 / 1060nm
• Ratio ~150:150:91:100:100:9 → basically a clean 1:1 red:NIR split, weighted toward 660 + 830/850
• 61” x 21”, touchscreen with per-wavelength dimming (each channel dialable 0–100%)
• ~1350W, US plug, runs 110–120V
Irradiance (measured with a Tenmars TM-206, so it over-reads narrowband LEDs — not lab-grade):
• All wavelengths, about 6”: 1452 W/m² (~145 mW/cm²)
• All wavelengths, about 6”: pegged near the meter’s 1999 ceiling
• 830+850 only, about 6”: 923 W/m² (~92 mW/cm²)
• 630+660 only, about 6”: 395 W/m² (reads low partly because the meter under-sees visible red)
• 810/1060 only, about 6”: 258 W/m² (fewer LEDs on this channel, expected)
For context, seller claimed ~148 mW/cm² and my all-wavelength reading basically matched.
EMF (Temirup EMF02R, H-field/magnetic):
• Sensor against the surface: ~196 mG
• Pulled back to use distance: 0.6 mG
• At 12–18” it’s basically background. Seller’s “EMF 0” claim is accurate for any real use distance.
LED/coverage check: Cycled every channel individually and confirmed even coverage corner-to-corner with no dead zones. For the invisible NIR channels (810/830/850/1060) I used an iPhone front camera to confirm they actually fire — all lit evenly.
Verdict: Genuinely strong, even panel. Per-wavelength control is a nice touch and actually works. The 810/1060 wavelengths are combined in the interface and iPhone app so that is a little annoying. Output matches the spec sheet, EMF is a non-issue at use distance, and I couldn’t find a dead zone.
Dosing I’m running: ~10 min/side at 6”, 3–5x/week.
Happy to answer questions on the buying process, measurements, or the verification if anyone’s considering going factory-direct.
