Just popped a channel on one of these nice little packs. (They really are kind of nice for what they are.)

What do you think about Lightronics dimmers?? I have 4 AS42D packs and they have been though alot and have never failed me and are about 8 years old. They have been rained on, snowed on, kicked, scrapped, overloaded and not one failure. I just picked up the XC 42 series and they have some pretty nice features such as dimmer curve settings, channel limiting and soft patching.

I have a number of these and the DP415 which is the 600W per channel unit and they both use the same TRIAC. I have only blown one TRIAC in normal use and it was an easy fix - 500W lamp failed. I have experienced this type of failure on other makes of dimmer in the entry to medium level price range.

I had one customer knock a Manfrotto stand over with a DP415 mounted on a T bar. Came down from 12 feet onto concrete. The impact caused two TRIACs to break in two. I replaced the two broken TRIACs and the unit still works great after 18 months. I also had another customer accidently connect phantom power into the DMX input via the sound snake - destroyed the SN75176 - the chip actually caught fire and burnt the board. Amazingly the only damage was the SN75176 the PIC was fine even though there was no optical isolation after the transceiver. Replaced the chip and the unit continues to work. I can't complain they are not bad for the price.

I normally replace the TRIAC with the highest current version I have that will fit when I change them on any dimmer.

The build standard is pretty good for the money and the parts are good quality - Texas Instrument etc.

I have used, sold and installed a lot of their products and have had very good experience with the company. Good stable products, great factory support and pretty innovative applications.
