Understanding when and how to replace parts helps maintain your device's effectiveness and safety.
Lamp/Bulb Replacement Guidance
When to Replace Lamps:
- Always refer to your User Manual for corresponding Lamp Part Numbers and the latest replacement information
- UVB Lamps: Approximately every 300 hours of use
- UVA Lamps: Approximately every 500 hours of use
Note: Lamp life varies depending on average treatment time and environmental conditions
Signs Your Lamps Need Replacement:
- Decreased treatment effectiveness
- Longer treatment times required
- Visible damage to lamps (cracks, blackened ends)
Important Safety Note:
- For devices that have been used for a while, ALL lamps must be replaced at the same time - never replace individual lamps in a machine that has been used. For NEW devices, when a lamp requires replacement (e.g., because it broke during shipping), replacing individual lamps is fine.
- New lamps must match original lamp specifications (Lamp Type)
- Prescription required for all lamp orders
- Replacement of lamps is easy; it should start with HCP for the prescription. Contact Phothera after they issue the lamp replacement prescription, using our contact form (link below), before attempting lamp replacement
- Some devices may require recalibration after lamp replacement, or a reduction in treatment of 50% if not recalibrated.
