Medium: 24″x12″ – Half-body coverage

Large: 36″x24″ – Full-body coverage

Modular systems: Connect multiple panels for custom setups

Key Features:

Irradiance/Power density: Measured in mW/cm², higher values = deeper penetration

Beam angle: Affects coverage uniformity

Cooling system: Fans or heat sinks for extended use

Mounting options: Stand, wall mount, or door hook

Pros:

Treat large areas simultaneously

Highest power output category

Versatile positioning options

Often modular/expandable

Cons:

Require dedicated space

Higher cost for quality units

Treatment requires stationary positioning

Recommended Specifications:

Irradiance: 100+ mW/cm² at 6 inches

Flicker-free operation

Quiet cooling fans

3. LED Hair Growth Caps

Best for: Androgenetic alopecia, hair thinning, scalp health

Hair growth caps (and helmets) are specifically designed to deliver therapeutic light to the scalp, stimulating hair follicles and promoting growth.

Design Variations:

Baseball cap style: Discreet, wearable design

Helmet style: Full scalp coverage

Band style: Targeted treatment zones

Key Features:

Number of diodes: 100-300+ for adequate scalp coverage

Wavelength: 650nm is optimal for hair growth

Fit system: Adjustable sizing for different head sizes

Treatment protocol: Automated timing and scheduling

Pros:

Discreet wearable design

Hands-free operation

Specifically optimized for scalp penetration

Often include hair growth tracking features

Cons:

Single-purpose device

Requires consistent long-term use (3-6 months)

May not fit all head sizes comfortably

Recommended Specifications:

200+ laser/LED diodes

650nm wavelength optimized for hair

Automatic shutoff after 20-30 minutes

Comfortable fit for extended wear

4. LED Therapy Belts and Wraps

Best for: Back pain, joint pain, muscle recovery, targeted body areas

Flexible LED arrays in belt or wrap form allow treatment of curved body surfaces and specific pain points.

Applications:

Lower back pain

Knee and joint therapy

Muscle strain recovery

Post-surgical healing

Key Features:

Flexibility: Conforms to body contours

Strap system: Secure positioning during treatment

Portability: Battery-powered options

Size options: Various lengths for different body parts

Pros:

Targeted treatment of specific areas

Flexible design adapts to body shape

Portable and travel-friendly

Often more affordable than panels

Cons:

Limited coverage area

May shift during movement

Lower power than stationary panels

Recommended Specifications:

Medical-grade LED flexibility

Adjustable straps with secure fasteners

Rechargeable battery option

Waterproof or sweat-resistant materials

5. Handheld and Portable Devices

Best for: Spot treatment, travel, budget-conscious users

Compact handheld devices offer portability and affordability for those wanting to try light therapy without significant investment.

Use Cases:

Wrinkle targeting

Acne spot treatment

Small wound healing

Travel companion

Pros:

Most affordable option

Highly portable

Targeted precision treatment

Cons:

Requires active holding/positioning

Limited coverage per session

Generally lower power output
