Borders on FRAUD

So I am basically satisfied with the device relative, but two things annoy me.
1) You have all 20 - have 30 pulses of light to cool the device relatively long. (Forced break because the unit shuts down)
2) The lamps last (namely at least 10 lamps counted) maximum from 1050 to 1130 light pulses. As the manufacturer to 1500 is absolutely incomprehensible for me. And that is an absolute impudence at the extremely high price in my eyes.
