Difference Between Light Engine Body, Shutter Barrel Assembly, and Lens Tube on an Ellipsoidal Fixture
When looking at ellipsoidal spot fixture, ETC breaks the fixture down into 3 main component parts.
1. Light engine body
2. Shutter barrel assembly
3. Lens tube
When ordering a new LED spot fixture you have the option of the Light engine body only OR light engine body AND shutter barrel. Lens tubes are always ordered as a separate part number with LED fixtures. Source 4 incandescent are the only product where an entire fixture with all 3 parts can be ordered under one product number.
Here are some common reasons to order the light engine body only:
1. Upgrading existing ETC incandescent Source 4 units to LED. You can reuse your existing shutter barrel assembly and lens tubes from your existing Source 4 fixtures and just purchase a new light engine body to complete the fixture.
2. If you are planning to use the 15°-30° or 25°-50° degree zoom lens permanently on your fixtures, the zoom lens have the shutter barrel natively built into them.
3. If you are planning to use the LED cyc adapter or LED fresnel adapter permanently on your Color Source or S4 LED fixture.
While the shutter barrel assembly is not required for the above applications, we suggest only ordering the light engine only model if your fixtures will permanently be used as zoom fixtures, cyc lights or fresnels. There is a very small cost savings by ordering the light engine body only, which is easily offset by the flexibility of being able to build additional spot fixtures when your zooms, cycs, or fresnels are not needed.
Here are common reasons to order the Light Engine w/ Shutter Barrel Assembly only:
1. When ordering new LED spot fixtures you will most likely want to specify the light engine with shutter barrel assembly. You will also have to specify a separate lens tube degree of your choice. ETC does recommend the EDLT lens tube to be used with the S4 LED and Color Source.
At the present time, the ETC incandescent Source 4 models are the only ellipsoidal spot fixtures you can order as a “complete fixture”. A complete fixture would include the Lamp Housing (“Light Engine”), shutter barrel assembly and desired lens tube which can be ordered under one part number.
