Average Reviews:
(More customer reviews)I have an ED-15 "Eliminator" dimmer pack. I didn't get it from Amazon. However, the description of this unit here on Amazon shows up with text that has nothing to do with the unit (and different descriptions each time: once it was for a video game, once for a video camera). Make sure you're looking at what you think you're looking at, before you buy.
The rest of this review is for the ED-15 I have, which is a 4 channel lighting dimmer, period - no video capability, no monsters, just a dimmer.
It works, but it has some issues. I like it because it has 4 analog inputs, which take 0-10v control voltages, to set the lighting brightness. This means it's easy to control from the sort of hardware you can make on your own, with a little knowledge of electronics.
As a dimmer under the analog line control, it's imprecise. When you vary the input control voltage, the brightness of the bulbs does follow, but erratically, and it takes a moment to settle at the new brightness. I used to own a Leviton dimmer that was rock solid and smooth in dimming, so I find the behaviour of this unit a little annoying in that regard. But it's a lot cheaper.
At one point there was a power flicker at my house, and all the lighting channels went into some bizarre mode where they all flickered very rapidly. I thought the device had fried, and it wasn't until I unplugged it and then, out of curiosity, plugged it back in, that I found out it had survived, and just needed to be power cycled. This makes me a little nervous about using it for long term unattended operation, though.
It drives the stated wattage without much noise (faint buzzing) and without getting very hot.
It works well with the (expensive) dimmable LED bulbs that are coming out.
All said, it's not a bad unit; I wish the dimming was smoother.
Addendum: I've starting using it with homebrew DMX control software, instead of the analog voltage lines, and it's rock solid under DMX, including being tolerant of slow DMX signals. (DMX devices are supposed to be tolerant of them, and it's nice when they are). Bumping this up to 4 stars. Note that it takes a 3 pin plug for the DMX, not the standard-mandated 5 pin - a common shortcut that many manufacturers take, and it saves a few pennies on cabling, but be careful you don't plug in a cable from audio gear by mistake, which often uses the same kind of 3 pin plug. You'll damage your gear.
