- Risk of Electric Shock: Always turn off power to the fixture at the circuit breaker or fuse box before installation, removal, or inspection.

- Do Not Exceed Wattage: Ensure the fixture's maximum wattage rating is not exceeded. This bulb is 43W.
- Handle with Care: Avoid touching the glass portion of the bulb with bare hands, as oils can reduce bulb life. Use a clean cloth or gloves if necessary.
2. Setup and Installation

- Turn Off Power: Locate the light fixture's power switch and turn it to the "OFF" position. For added safety, turn off the power at the main circuit breaker or fuse box.

3. Operating Instructions
The Eiko Halogen A19 bulb operates like a standard incandescent bulb. Once installed, simply use the light fixture's switch to turn the bulb on or off.
- Instant On: The bulb provides instant full brightness upon activation.
- Light Quality: This halogen bulb produces a brighter, whiter light compared to traditional incandescent bulbs, enhancing visibility and color rendition.
- Dimming: If used in a dimmable fixture with a compatible dimmer switch, this bulb can be dimmed. Ensure your dimmer is rated for halogen or incandescent loads.
4. Maintenance
Minimal maintenance is required for your Eiko Halogen A19 bulb. However, following these guidelines can help ensure optimal performance and longevity:
- Cleaning: If the bulb becomes dusty, ensure the power is off and the bulb is cool. Gently wipe the glass with a clean, dry, lint-free cloth. Do not use liquid cleaners.
- Replacement: Halogen bulbs, like all light sources, will dim over time and eventually burn out. For consistent light output, consider replacing bulbs when a noticeable decrease in brightness occurs. It is often recommended to replace bulbs in multi-bulb fixtures at the same time for uniform light.
- Handling: When replacing, avoid touching the new bulb's glass with bare hands. Oils from your skin can create hot spots and reduce bulb life. Use a clean cloth or gloves.
