Safety & Handling Guidelines
- Burn Position: Horizontal only. Operating outside of the horizontal plane will lead to premature filament failure.
- Skin Contact: Do not touch the quartz glass. Oils from your skin can cause "hot spots," leading to "blistering" and rupture. If touched, clean with alcohol.
- Enclosure Requirement: Use only in fixtures designed to contain glass fragments in the rare event of a lamp failure.
