Concentric Ring Top Hat (City Theatrical)

When space is at a premium, Concentric Rings are often the designer's first choice for beam control.  Concentric Rings deliver 45° cutoff for full control of stray beams and spill, like a full Top Hat, but they do it in a shorter device.  Concentric Rings also provide a "Svoboda-like" style when used on lighting fixtures that are in view of the audience, and present a deeply theatrical feel.  Designed for the fixtures below, and should work on other fixtures* which use the same media frame size.  Use with caution on LED fixtures without a fully homogenized beam, color shifts may occur.

• Offers full control of stray beams and spill
• Comparable to full 6" Top Hat, but only 2" long!
• Fabricated from light gauge steel with hemmed edges
• Works great with:

  • Altman 6" Fresnel
  • Altman PAR 56
  • ETC ColorSource Fresnel
  • ETC Desire Fresnel
  • ETC fos/4 Fresnel
  • ETC Source Four PAR(nel)
  • ETC Source Four Fresnel
  • ETC Source Four LED Fresnel Adapter
• Works with, but may exhibit color shifts:

  • ETC ColorSource PAR *
  • ETC Selador Desire D40 * / D40XT * (except XTI)
  • ETC Source 4WRD PAR(nel) *
• * Color may shift on LED Fixtures without a homogenized beam.  This is due to the many source of light, especially on fixtures without in-lens color mixing.
• Not for use with ellipsoidal/profile (hard edged) fixtures, will distort the beam
