The tungsten fresnel is a classic fixture that is very simple and reliable, not to mention easy to fix. It’s 3200k and all of these lights are very hot to the touch. While they are hot, it is possible to operate all of them without gloves by only touching the t handle and the flood spot knob to pan and tilt it.

- ARRI 1000+ - 1KW - 7 3/4" Scrims
- ARRI 2000 - 2KW - 9" Scrims (Studio Model)
- Mole 2801 - Mini Mole - 200W - 3" Scrims
- Mole 2821 - Tweenie - 650W - 5" Scrims
- Mole 407 - 407 - 1KW - 6 5/8" Scrims
- Mole 3081 - Baby 6" - 1KW - 6 5/8" Scrims
- Mole 4131 - Baby Jr - 2KW - 9" Scrims

- Mole 4351 - Baby Sr - 5KW - 13 1/2" Scrims
- Mole 4181 - Baby Tener- 10KW - 18 1/2 Scrims
Uses
Tungsten fresnels have a wide range of purposes throughout their wattages. 650w and below can be used as accents, a fill light, or a key light if used in close proximity. There are larger fresnels that range from 1k all the way up to 20k watts.
The entire instrument consists of a metal housing, a reflector, a lamp assembly, and a Fresnel lens. Many Fresnel instruments allow the lamp to be moved using the spot/flood knob, to increase or decrease the size of the light beam. As a result, they are very flexible, and can often produce a beam as narrow as 7° or as wide as 70°. The thing that makes the fresnel a relatively consistent intensity across the entire width of the beam of light.
QC Process
- Clean reflector if necessary (use alcohol wipe)
- Test Spot/Flood knob - should be smooth.
- Check fresnel
Accessories
Fresnels have Barndoors and typically a set of 5 metal scrims: 2 full Double, 1 Full Single, 1 Half Double, 1 Half Single in a bag.
Troubleshooting
If a light won’t turn on it usually will be 1 of 3 problems.
- Bad switch that must be replaced
- Bad wiring in switch
- Bad wiring in head
Use a continuity meter to check and see if you have electrical continuity between each section.
