Breaking Down the Features of Sea-Dog 441093-1 Sea Dog Single Contact Bayonet Base Light Bulb 15 Candle Power
Specifications
The Sea-Dog 441093-1 Sea Dog Single Contact Bayonet Base Light Bulb 15 Candle Power is a precisely engineered component designed for specific applications. Its core specifications include a single-contact bayonet base, which ensures a secure and positive electrical connection. The nickel-plated brass base is a crucial detail, providing excellent corrosion resistance, which is vital in marine and other harsh environments.
The bulb itself is housed in heavy-duty glass, designed to offer superior break resistance compared to more fragile alternatives. This robust housing, combined with a resilient filament, is engineered for extended longevity. The operational voltage is specified as 12.8 VDC, aligning with common marine and automotive electrical systems. Its physical dimensions are approximately 1-7/8″ in height and 1″ in width, making it suitable for compact fixtures.
The light output is quantified as 15 Candle Power, a traditional unit of luminous intensity that, for this bulb’s wattage, translates to a useful, practical brightness. It draws 13.3 Watts of power, resulting in an amperage draw of 1.04 Amps at its rated 12.8 Volts. These specifications collectively indicate a well-balanced design for its intended purpose, offering a good compromise between light output, power consumption, and durability.
Performance & Functionality
In its primary role, this bulb performs exceptionally well. The 15 Candle Power output is more than adequate for its intended use as a navigation or indicator light, offering clear visibility without being overly power-hungry. Its functional consistency is a significant strength; once installed, it simply works, providing reliable illumination without flickering or dimming.
The most significant strength of this incandescent bulb is its straightforward, no-nonsense operation and its build quality that withstands demanding conditions. A minor point of consideration, inherent to all incandescent bulbs, is their operational lifespan compared to modern LEDs; however, within its category, this bulb appears to be a top performer. It meets and, in terms of build quality, potentially exceeds expectations for an inexpensive replacement part.
Design & Ergonomics
The design of the Sea-Dog 441093-1 Sea Dog Single Contact Bayonet Base Light Bulb 15 Candle Power is functional and robust. The nickel-plated brass base is a standout feature, offering a premium feel and superior corrosion resistance. This material choice significantly enhances the bulb’s suitability for environments where rust and oxidation are constant concerns.
The overall build feels solid and well-constructed. The heavy-duty glass bulb housing provides a tactile sense of durability, suggesting it can handle minor impacts or vibrations better than thinner-walled glass.
