800W tungsten spotlight with 150mm Fresnel lens by Strand Electric, delivering 2000 lux at 3m distance; compact at 2.3kg.
Technical Details
The Redhead uses an 800W tungsten-halogen lamp (type P2/28 or GY9.5) and features a continuously adjustable Fresnel lens system with a 150mm diameter. The aluminum housing typically measures 280 x 220 x 320mm with a weight of approximately 2.3 kg without a stand. The reflector is made of polished aluminum with a parabolic curve. The light output is around 18,000 lumens in spot setting, corresponding to an illuminance of approximately 2000 lux at 3 meters. Modern variants offer barn doors, color gel holders, and DMX control.
History & Development
Strand Electric introduced the first Redhead in 1962 as a cost-effective alternative to larger studio spotlights. The breakthrough came in 1968 with the introduction of the more compact series for the emerging independent filmmaking scene. In the 1980s, manufacturers like Arri, Ianiro, and Mole-Richardson adopted the concept and developed their own 800W Fresnel versions. Since the 2000s, LED counterparts have emerged with comparable light characteristics but significantly lower power consumption and heat generation.
Practical Use in Film
Redheads form the backbone of many low-budget productions and documentaries. Cinematographer Roger Deakins used them in "Fargo" (1996) for interior shots to enhance the cold atmosphere with hard side lighting. Typically, three to four Redheads are arranged as a three-point lighting setup: key light, fill light, and backlight. Their shallow depth of 22cm allows for use in confined shooting locations. Disadvantages include high heat generation (housing temperature up to 85°C) and continuous lamp replacement with intensive use.
Comparison & Alternatives
The Redhead is positioned between the weaker Blonde (2000W) and smaller Dedolights (150W). LED alternatives like the Arri L7-C or Aputure 300d offer similar light output with 95% less power consumption and stepless color temperature adjustment. For daylight exterior shots, HMI spotlights are better suited due to their 5600K color temperature. However, the classic Redhead remains the standard for quick, uncomplicated lighting setups without extensive power supply requirements.
