and yes I own it
The first show I used it on last year (tiesto in atlanta 2006). About halfway through the show it quit turning all the way off. 50mw output when 0 volts applied to it. This is an analog version of the laser. The laser has since gotten worse. Now with 0 volts it puts out between 300 and 800mw of power at random, ask adam, he saw that over the weakend. On the semi-plus side with the increase of "blanked" status, It outputs more and more power as the blanking goes out so right around now my 1 watt gets between 1.2 and 1.5 watt when 4.72 volts is applied. Anyhow, this is what shutters are for and why you should have one.
Before anyone ask me to check to make sure my dac is outputting 0 volts. I have already done so. I have also completely disconnected the blanking wire to no avail. We will see what extreme lasers does for me since I bought it from them. That will be a whole new review in the sellers section.
After talking with fred from one stop laser shop, he told me he has had this occurred on a few CNI lasers so beware. So far it has yet to occur on either one of my TTL version of the CNI lasers so it might be a problem within their analog circuitry. I am sure there is a pot inside the PS that can be turned to get this corrected but I dont want to void the warranty.
When its all said and done, the CNI 1 watt still puts out well over a watt and has not shown any signs of weakness in its output. Nor does it ever get warm
