Buying Guide: Key Purchase Considerations
- Compatibility: Confirm your light’s brand and exact model series (Attwood, Seachoice, Perko) before ordering. Many covers specify compatible series and will not fit telescoping or non-all-round fixtures.
- Size and Fit: Check outer diameter, inner diameter, and height. Typical universal caps are around 1.9″ OD, 1.5″ ID, and 2″ tall; some models differ (2.5″ variants exist) and may not seal properly.
- Material and Durability: Look for polycarbonate or similarly tough, impact-resistant plastics rated for marine use to withstand UV exposure and saltwater. A frosted, anti-glare lens reduces glare without sacrificing range.
- Visibility and Safety: A 360-degree frosted globe improves nighttime visibility and reduces eye strain, contributing to safer navigation during low-light conditions.
- Installation: Screw-on designs offer straightforward replacement. Ensure gasket integrity to prevent water intrusion; check for any required tools or seals.
- Applications: Pontoon boats, hardtops, radar arches, and boats up to 20 meters (65 feet) often share compatible 2-inch or 1.9-inch globes. When in doubt, compare with a current globe’s dimensions.
- Limitations: Some covers exclude certain models (e.g., 5610-48-7 telescoping All Around Light). Always confirm model compatibility to avoid returns.
FAQ
- Q: Will these covers fit all stern lights on my pontoon? A: Not always. Most covers fit Attwood or Perko All-Round fixtures; check your light’s model or series first.
