Updated September 2026. Prices and model specifications below were checked against active Hooga product records on September 28, 2026 and may change. Follow the linked product page for the current offer.
Short answer: Choose HG if you want a straightforward red/NIR panel at the lowest entry price; PRO if you want a dual-chip 660/850-nm panel with higher listed six-inch irradiance in comparable sizes; and ULTRA if you value four wavelengths (630, 660, 810 and 850 nm) and additional controls. Those differences are real product features, not proof that one series delivers better health outcomes. First choose the area you need to illuminate and a format you will use consistently, then compare the specific models below.
Key takeaways
- The three series are not a simple good/better/best ladder. HG, PRO and ULTRA emphasize price, listed output and controls differently.
- HG300 is 73 mW/cm² at six inches, as stated on its current product page. Do not assume all HG models deliver at least 90 mW/cm²; the HG200's six-inch figure is being reconciled.
- Prices are a snapshot, not a promise. The live product links are authoritative for checkout pricing and availability.
- Manufacturer-stated irradiance at one position is not the same as a clinical outcome or an absorbed tissue dose. Use our dosage guide to interpret the number.
How do HG, PRO and ULTRA differ?
| Series | Core light mix | Hardware emphasis | Choose it when... |
|---|---|---|---|
| HG | 660-nm red and 850-nm near-infrared | Single-chip LEDs, simpler panel controls, lowest-priced entry model | You want a basic, practical panel and can choose the size that covers your intended area |
| PRO | 660-nm red and 850-nm near-infrared | Dual-chip LEDs and generally higher listed six-inch irradiance than comparable HG models | You want the two-wavelength approach with more output at the stated measurement position |
| ULTRA | 630/660-nm red and 810/850-nm near-infrared | Quad-chip design and controls such as brightness and pulse mode on listed models | You want more wavelength and control options, with a higher equipment budget |
More wavelengths or more mW/cm² do not automatically improve a result. A review of photobiomodulation parameters emphasizes that wavelength, irradiance, time, beam geometry and treatment target interact; product specifications alone cannot establish an effective dose for everyone (Zein et al.). For the wavelength distinctions, see the complete wavelength guide.
Which models are currently in the lineup?
The figures below are Hooga-listed irradiance at six inches, not third-party testing or a dose at your preferred distance. Price is the active base-variant price observed September 28, 2026. Product pages can change; verify the linked page before purchasing.
HG series
| Model | Format | LEDs | Listed irradiance at 6 in. | Price checked Sep. 28 |
|---|---|---|---|---|
| HG200 | Compact targeted panel | 40 | Pending specification review | $149 |
| HG300 | Compact targeted panel | 60 | 73 mW/cm² | $199 |
| HG500 | Mid-size panel | 100 | 94 mW/cm² | $359 |
| HG1000 | Larger panel | 200 | 98 mW/cm² | $599 |
| HG1500 | Larger panel | 300 | 115 mW/cm² | $899 |
The HG200 product page currently gives inconsistent six-inch irradiance figures across its features, comparison chart and technical details. We have left its number blank here rather than repeating a value we cannot reconcile. HG300's approved six-inch figure is 73 mW/cm², and the two panels also differ in LED count and size (HG300 product page).
PRO series
| Model | Format | LEDs | Listed irradiance at 6 in. | Price checked Sep. 28 |
|---|---|---|---|---|
| PRO300 | Compact targeted panel | 60 | 109 mW/cm² | $299 |
| PRO750 | Mid-size panel | 150 | 183 mW/cm² | $599 |
| PRO1500 | Larger panel | 300 | 189 mW/cm² | $1,199 |
| PRO4500 | Full-body single panel | 900 | 168 mW/cm² | $2,999 |
The PRO300 is a more useful direct comparison with HG300 than comparing only PRO750 against HG500. Both compact models list 660/850-nm light and 60 LEDs, but their LED design, controls, stated six-inch output and price differ (HG300; PRO300). The current PRO4500 is a 900-LED full-body panel, with a listed six-inch irradiance of 168 mW/cm². That specification describes a measurement position, not a uniform dose at every point over the body.
ULTRA series
| Model | Format | LEDs | Listed irradiance at 6 in. | Price checked Sep. 28 |
|---|---|---|---|---|
| ULTRA360 | Compact targeted panel | 72 | 136 mW/cm² | $399 |
| ULTRA750 | Mid-size panel | 150 | 161 mW/cm² | $799 |
| ULTRA1500 | Larger panel | 300 | 165 mW/cm² | $1,399 |
| ULTRA4500 | Full-body panel | 900 | 165 mW/cm² | $3,999 |
ULTRA's four listed wavelengths expand the selectable light mix, but “four” is not a treatment-outcome score. If your goal is a specific skin or recovery outcome, read the relevant evidence and the model's instructions rather than inferring success from the number of LED chips. The red-versus-NIR guide explains the two light categories.
What matters more than the largest irradiance number?
Coverage and position. A compact panel can be a good fit for a small target but may require repositioning for a larger area. A taller or multi-panel setup changes coverage and space requirements. Check dimensions and stand compatibility on the exact product page, not just its wattage-class name.
Usable controls. Decide whether you need separate red/NIR selection, brightness adjustment or pulse mode. Additional modes add flexibility; they do not by themselves establish superior clinical results.
A repeatable dose framework. Irradiance is measured at a stated distance. The light reaching your skin can vary across a panel's footprint, and surface J/cm² is not absorbed tissue J/cm² (Hadis et al., radiometry review). Our panel-distance guide explains what you can and cannot infer when changing position.
Actual cost and practicality. A smaller panel that fits your room and routine may be a better purchase than a larger setup you will not use. Compare the current price, warranty, return terms, physical size and accessories on each linked product page.
Which should you choose for common setups?
| Your decision | Sensible models to compare | Why |
|---|---|---|
| Lowest-cost starting point | HG200 vs. HG300 | Both are compact HG panels; compare LED count, size and actual space needed |
| Compact panel with more listed output | PRO300 vs. ULTRA360 | Compare two versus four wavelengths and controls as well as price |
| Mid-size home panel | HG500 vs. PRO750 vs. ULTRA750 | Choose based on coverage, desired controls and budget, not irradiance alone |
| Larger single panel | HG1500 vs. PRO1500 vs. ULTRA1500 | Compare dimensions and light mix before paying for additional features |
| Full-body single panel | PRO4500 vs. ULTRA4500 | Compare wavelengths, controls, footprint, mounting and instructions |
These are Hooga product-selection suggestions, not an independent third-party ranking. A panel is also not the right format for everyone: compare a face mask with a panel if your use is face-only, or browse all red light therapy devices if you want a targeted or wearable format.
Frequently asked questions
Is PRO always better than HG for recovery?
No such clinical comparison has been established for these specific products. PRO lists different LED architecture and generally higher six-inch irradiance in comparable sizes; outcome evidence from localized photobiomodulation studies should not be assumed to validate a home panel (whole-body exercise evidence review).
Does ULTRA's four-wavelength mix mean it works twice as well?
No. Wavelength count is a hardware description, not a measured benefit. Other parameters and study endpoints matter (Zein et al.).
Do I need the largest panel?
Not necessarily. A small area can be illuminated with a compact panel, while larger areas may require repositioning or a larger format. Choose around your physical space and intended coverage first.
