A compact, budget 60-LED panel for targeted 660/850 nm sessions, with irradiance stated at 6 inches.
By the RecoveryScored editorial team · Reviewed 2026-05-30
Bottom line
In our scoring, Hooga HG300 earns 8.0 out of 10 (Strong). Independent testing puts its irradiance at about 55 mW/cm2 at a 6 inch treatment distance, below its 73 mW/cm2 headline, so judge it on the measured figure. It rates highest on emf & flicker (10.0/10). This is informational only, not medical advice.
Our take
Hooga HG300 scores well overall, at 8.0 out of 10. It is strongest on EMF & Flicker (10.0/10) and weakest on Build & Coverage (3.0/10).

How it scored
Verified Irradiance
8.0/10 · 30%Power density at a real treatment distance. Independent measurement at 6 in is prized; a number with no stated distance is not a usable spec.
- +5Independently measured at 6 in A55 mW/cm² (Light Therapy Insiders) - Irradiance is independently measured at a real 6-inch treatment distance, not a manufacturer surface reading.
- +3Effective irradiance in the studied range B55 mW/cm² at 6 in - Delivered irradiance at 6 in falls in the range used in most clinical studies (roughly 30-160 mW/cm²).
Wavelengths
8.0/10 · 20%Delivery of the clinically studied red (660 nm) and near-infrared (850 nm) bands.
- +3Red 660 nm present A660 nm - Includes the 660 nm red band used in skin and surface studies.
- +3Near-infrared 850 nm present A850 nm - Includes the 850 nm near-infrared band used in deeper-tissue studies.
- +2Dual red + near-infrared B660 + 850 nm - Combines red and near-infrared, the most studied pairing.
EMF & Flicker
10.0/10 · 15%Low EMF at the treatment distance and freedom from visible flicker / ripple.
- +6Low EMF at treatment distance Bnear background at 6 in - Electromagnetic field is at or near background at the treatment distance.
- +4Flicker-free operation Bno measurable flicker - Runs without visible flicker or significant ripple.
Value
10.0/10 · 20%Computed cost per treatment area vs the panel-size class median. The number brands do not put side by side.
- +8Cost per treatment area vs class A$0.31/cm² (bottom 20% of class (best value)) - Price divided by emitting area, scored against the panel-size class median.
- +2Delivered-light value computable B$0.006/mW delivered - Because irradiance is given at a usable distance, real delivered light per dollar can be computed.
Build & Coverage
3.0/10 · 15%Treatment area, total power, warranty, and whether any FDA clearance is real (510(k)) vs a registration listing.
- +1Targeted coverage Btargeted panel - Sized for targeted areas (joints, face) rather than whole-body sessions.
- +2Solid warranty B3-year warranty - Three-year or longer warranty.
What to know before buying

FAQ
- Does the HG300 need a separate stand?
- No, it has a built-in swing-out kickstand for tabletop use, though it can also be hung.
- How does it differ from the PRO300?
- The HG300 uses single-chip LEDs rated at over 73 mW/cm² at 6 inches, while the PRO300 uses dual-chip LEDs rated at over 109 mW/cm² at 6 inches.
