Confirm before ordering

Match OSRAM product number 11520 and ANSI code ECT. Confirm 500W, 120V AC, E26 base, fixture wattage rating, and available clearance; an E26 socket alone does not establish safe compatibility.

Equipment compatibility

Compatible-equipment references

The following references are limited to versions documented for an ECT 500W 120V photoflood lamp. Confirm the fixture label because similarly named equipment may have different voltage or heat limits.

  • Smith-Victor FL10 floodlight
  • Smith-Victor FL14 floodlight
  • Mole-Richardson Cinelite 500W / Type 16
  • Photogenic DigiLight CL500 continuous-light fixture
  • Professional photographic, darkroom, and projection fixtures explicitly specifying ANSI ECT at 500W and 120V

Do not install in a household fixture or any socket not explicitly rated for this lamp's 500W heat load and dimensions.

Cross-reference guidance

Match ANSI ECT

Cross-brand ECT lamps may share the 500W, 120V, E26 photoflood identity, but dimensions and package references can differ. No separate in-stock Dynamic Lamps product is linked here as an exact alternative.
