Illinois Nail Technician Practice Exam 2026 – Complete Prep Guide

The correct choice indicates that manicure bulbs should be changed every 3-4 months. This timeframe allows for consistent performance and ensures that the bulb emits adequate light for the nail technician to work effectively. Over time, the brightness and intensity of light from bulbs can diminish, which can affect the quality of services provided in a manicure or any nail care appointment.

Regularly changing the bulbs within this 3-4 month window helps maintain optimal conditions for accurately assessing nail health and applying products. It also supports the overall hygiene and safety of the tools used, as old bulbs may harbor bacteria and reduced effectiveness. By following this guideline, nail technicians can uphold industry standards and provide their clients with the best possible experience.
