About four months ago, I purchased a four pack from
Bulb America, the same as Derek. I bought the $69.95 and got a Matrix with
LCD display. I was just checking their site and the Matrix is listed at $129.95. I was directed to this site by somebody on either the Control booth or the light
network, I don;t remember which. They stated that they had ordered the $69.95
Bulb America and got an Elation. I think that
Bulb America sends you what ever they have the most of, but for the price that you pay. All of these
shoebox dimmers that they show on their website, are basically built by the same company and relabeled to different names. ELation, Chavet, Matrix and others. I love the
unit I got, we have used it for practicals on almost every production since it's
purchase. Just don't over load any one
channel, because the Triacs don't have much
headroom. If you treat these guys well, as far as loads they are rugged and will last a long time. Also the Triacs are easily replaced with higher quality ones from mouser if the needed . I
build a lot of the dimmers that we use in our
theatre, and just the logic circuitry and drivers cost me as much as the entire
dimmer pack from
Bulb America. I would easily
purchase more of them in the future, if it wasn't for the fact, that I have built more dimmers than we have instruments at the present time.
