Why Selador
ETC’s Selador Fixtures provide many ways to wash a stage in colored light using less electrical
energy. LED technology means lower HVAC costs due to lower heat and removes the need
for maintenance and material costs to replace lamps and color media. Additionally, the
traditional Red – Green - Blue fixture method provides only a limited color palette. Selador’s
x7 Color System gives the lighting designer an entire swatch book of colors for the stage.
Overview
This is a best practice guide for replacing border lights in existing applications. This is also a guide
for creating stage washes in new applications.
This guide describes the suggested placement of Selador series LED fixtures to wash stages in
colored light. For white light washes, it is suggested that an ETC PAR is added to the wash.
The following wash suggestions utilize mounting heights of 20 feet for the Paletta and 20 and 30
feet for the Vivid line of fixtures. Many other combinations are possible, especially utilizing the
secondary lens options for the Selador series.
Illumination represented in the graphics throughout this document are foot candles (fc) at the
specified throw and distance between fixtures. One foot-candle (fc) ≈ 10.764 lux.

field measurements in
foot-candle (fc)
All foot-candle readings are given in white light. Selador series LED fixtures are most effective and
efficient in colored light, therefore are most often brighter than an incandescent fixture
that has been gelled.
