650W R7s Halogen Bulb
This 650-watt halogen lamp uses an R7s recessed single-contact base and a double-ended design. It operates at 120 volts and produces a 3200K colour temperature. The bulb suits fixtures that require a high-output linear halogen source.
3.1-Inch Linear Construction
The maximum overall length is 3.1 inches, so the lamp fits only fixtures built for this specific dimension. The double-ended shape demands a matching socket at each end for secure electrical contact. Build quality follows the Bulbamerica specification for standard halogen replacement use.
100-Hour Rated Life
The lamp is rated for 100 hours of operation before replacement is needed. This short lifespan makes it suitable for intermittent or specialised lighting tasks rather than continuous daily use. Buyers who need longer maintenance intervals should consider alternative technologies.
