To maintain best performance, the lamp module should be replaced after approximately 18-24 months.
To replace the lamp module, unplug Aclare from the wall outlet. Firmly grip the base with one hand and the lamp module with the other, and pull apart until the lamp module unplugs from the base. Firmly grip the base with one hand and the new lamp module with the other. Align the two components and push them securely together.
