    I just found that the COLORsplash Jr. and my "generic, diamond-pattern LED P64" will "hold last DMX," but the Solaris model won't. Something to consider, may not be at all important to some, may be very important to others.

    [user]Phil000[/user], in the wedding thread we were discussing one use of LED PARs as uplighting around a tent/ballroom. I suggested taking a bunch on floor bases, plugging them into the nearest wall socket, then walking to each one with a Pocket Console®, and setting the desired color, then moving onto the next. No data run required.

    "Hold last DMX," also known as "Hold Last Look," is a feature implemented on many dimmer racks. On a Sensor system, the user can set the "hold" time in case of loss of DMX from 1 sec. to infinity. (Great for switching consoles.) Some moving lights also have this capability built in, others shut themselves down immediately upon loss of DMX.

    Anyone have the Chauvet LEDRain 64? I just looked at the specifications, and its footcandles gets crazy.

    (And apparently I've been calling my unit the wrong name all along?)

    Footcandles of lower end Chauvet LED lights.
    As listed on their website.

    LEDsplash Jr: 39

    LEDsplash 196: 75

    LEDsplash 200B: 86.4

    LEDrain 64: 292

    Too bad the LEDrain 64 looks bad, because it seems to have the output to back-itself up. I couldn't find a good idea of prices online, but it seems that the LEDrain 64 and LEDsplash 200B are similarly priced... what gives? What's the difference?

    Charc, footcandle readings mean nothing without a specification of distance. The manufacturer may say 39 footcandles, but that must be at one foot, as mine measured 4-5 FC at 15 feet.

    Just measured mine again: as best I can tell, that 39 number must be for 5', but it's hard to tell as the beam is so uneven.

    Take a look at the beam angles (45 degrees for 200B, 16 for Rain64).

    Just a word of caution on this. Very often times many venues will have several outlets that share one breaker, some you might not even see out in the lobby or ajoining room. Hotel/catering staff will just plug in their coffee pots or what not into the first available outlet and often times, this can lead to blown breakers.

    Recently we had video company we were working with lose one of their big video screens suddenly for seemingly no reason. It doesn't take them much time to realize that the outlet the projector was on was dead. Finlay, after switching power around, they get it back online after a few minutes later, enough time for the client to come back an start breathing over people's shoulders. Turns out that the hotel had plugged in the heat lamps of their meat carving stations in the lobby. The outlet was apparently linked to the one in the wall in the room that their projector was on.

    The moral of the story being, you never know when you might have power problems. People are going to be a bit annoyed if you have to go kneeling down to program every single light in the middle of reception or party to get them back on after the coffee pot you didn't see on your cube tap trips the breaker.

    Point taken, but I don't think a 0.03A LED fixture is going to put a circuit over the edge. The caliper of parties we're talking about will not accept paying a hotel charge of $500 for a 100amp 120/208VAC 3Ø power drop, not to mention the distribution equipment, or the cables across doorways.

    [user]JD[/user]'s signature is classic: "Oh, that switch also feeds the hotel?" We've all been there.

    The device - usually a dimmer rack, will hold the look it's currently putting out (power to lamps, or the mix and intensity of the LED's) should the DMX data be removed/lost

    Usually user definable in the setup menu - forever/600 seconds, none, etc...

    Since it's come up Bill did you use hold or run data to all those fixtures (and why if you feel wordy)???

    In this instance they were operated via Light Jockey.
