What Is UVB, and Why Is It Different?
The BioShield 60-LED Standee (BK300) is the only device in the Lufalight lineup that includes a regulated UVB lamp alongside its red and near-infrared LED array. UVB (ultraviolet B) is a different part of the light spectrum entirely from the red and near-infrared light covered in our PBM science guide — and it interacts with the skin very differently.
Unlike red/NIR light, which is generally considered safe for frequent, longer sessions, UVB exposure needs to be carefully measured and gradually increased. This is the same principle behind any UVB-emitting device, medical or otherwise: start low, go slow, and never exceed the manufacturer's exposure guidelines.
Getting Started Safely
Before your first session with the BK300's UVB function:
- Read the included exposure chart. Your BK300 comes with a specific exposure time chart based on skin type — follow it exactly, especially for your first several sessions.
- Start with the shortest recommended time. Even if you have a tan or naturally darker skin tone, begin with the minimum exposure time on the chart to see how your skin responds.
- Maintain the recommended distance. Standing too close increases intensity beyond what the timer accounts for.
- Use eye protection if specified. Follow the device's instructions regarding eye protection during UVB sessions.
Building Up Exposure Time Gradually
UVB exposure guidelines typically follow a gradual build-up schedule:
- First 1-2 sessions: Use the minimum time on your skin-type exposure chart.
- Following sessions: If no excessive redness or irritation occurred after 24 hours, you may gradually increase exposure time according to the chart's progression — never jump straight to maximum exposure.
- Maintenance sessions: Once you've reached your appropriate exposure level, space sessions out as directed rather than increasing frequency.
If you ever experience redness, irritation, or discomfort that persists beyond a normal mild reaction, stop using the UVB function and allow your skin to fully recover before resuming — and consult a physician if irritation is significant or doesn't resolve.
Combining BK300 with Red & NIR Therapy
One of the advantages of the BK300 is that its red and near-infrared LEDs can be used independently of the UVB lamp — meaning you can use the device for standard PBM sessions (as described in our PBM science guide) far more frequently than you'd use the UVB function.
A common approach:
- Use the red/NIR panel for regular full-body sessions (similar frequency to the BodyMax series or ClinicalEdge E300).
- Use the UVB lamp only according to your exposure chart's recommended schedule — typically far less frequently than red/NIR sessions.
- Never run a UVB session immediately followed by intentional sun exposure on the same day, as this can compound UV exposure beyond intended levels.
Who Should Avoid UVB Exposure
In addition to the general precautions in our safety guide, UVB exposure specifically warrants extra caution for:
- Anyone with a history of skin cancer or precancerous skin conditions
- Anyone taking photosensitizing medications (certain antibiotics, acne medications, etc. — check with a pharmacist or physician)
- Individuals with conditions that make skin especially sensitive to UV light
- Children, without direct guidance from a physician
As always, the BioShield 60-LED Standee is a wellness device and not intended to diagnose, treat, cure, or prevent any disease. When in doubt about whether UVB exposure is appropriate for you, consult a physician before use.
