Sounds like Pica Cubes might could do this.... http://us.rosco.com/en/product/pica-cube-4c 12VDC-24VDC powered, take DMX in, RGBW LED avail, 2.5"x2.5"x3.6" long (small easy to build-in), and has accessory mounting capability that could be used for globes. I'm an engineer with TheBlackTank, the...

also Rosco's Braq Cube.. http://www.rosco.com/luminaires/braqcubes.cfm Very bright, very good dimming, manually changeable lensing included (20-60degree), very high pwm rate (4Khz)

Here's a recent article about a new Broadway show (School of Rock) using them (see gear list at end, 20 Rosco Miro Cube 4C RGBW): http://plsn.com/current-issue/73-inside-theatre/19208-lighting-broadway-s-school-of-rock.html There's been lots of theatrical applications.. One of the higher...

Agreed.. It was a specific request from a customer. I don't know exactly why they asked for this, but I'm guessing they don't have DMX infrastructure on his set (I think it's some kind of TV production set) and they want to install some DMX controlled lights. I spent a little time searching for...

Does anyone know of a box that will take dimmed AC mains in, and as a result, send out a DMX data stream that can be used to run a light such that the light appears to be being dimmed by the original AC mains dimmer? I can't seem to find one of these, but I suspect they must exist.... Thanks in...

Hi.. I'm an engineer for Black Tank, the company that developed the Miro cube. Jack Burwick is the Rosco Product Manager for LED Systems ([email protected]). He'd be able to help if you end up having trouble getting a 4C to evaluate. In the meantime, if there's anything technical I can help...

Would these be a possibility? https://www.rosco.com/lighting/mirocube4c.cfm?menuReturn=lighting They come standard with a lens set that includes a 60 degree flood. MSPR is $875, but I think you can get them for less than that.

One of my colleagues (an ex CK guy) suggested a Pharos LPC4 as a possibility. http://www.pharoscontrols.com/products/lighting_controllers/lpc

The Rosco Miro Cube 4C is a 'tri' type with 4 color RGBW. MIRO CUBE™ 4C - rosco.com

The "pop on" problem you're talking about isn't with the LED's in the fixture, it's with the electronics that control them. Most LED fixtures use PWM to control the brightness of the LED's. As was stated, PWM is a scheme where the LED's are turned "on" and "off" fast enough that you can't really...

A PhotoVoltaic Isolator maybe? These are pretty interesting little devices that take a low level DC input signal and use a PhotoVoltaic process to generate an isolated DC voltage output. http://www.irf.com/technical-info/appnotes/an-1017.pdf page 3 of that pdf shows how to use a PVI5080N to...

These are very nice on track: MIRO CUBE™ WNC - rosco.com All the variations of Miro Cubes ("WNC"=variable color temperature white, "4C"=color changing, and "UV"=black light) can be track mounted.. the white (shown in the link) is the only one with a picture showing it on track. They take AC...

An intermittent caused by temperature cycling is most likely an IC. On the inside of those chips are a die (the silicon logic/smart part) but there are also very fine wires that connect spots on the die to the legs of the IC. Those wires are "bonded" ( Wire bonding - Wikipedia, the free...

These might work: MIRO CUBE Overview - rosco.com These have been around for a couple of years and were known as Black Tank Brickblasters. Now that Black Tank & Rosco have teamed up, they're being sold as Rosco Miro Cubes. They're a 4" cube, weigh 2lbs and have equal (or better) lumens, and a...

If you're an ebay'er, try searching for "PWM controller". Here's an example of one: PWM Dimming Controller For LED Lights or Ribbon, 12 Volt 8 Amp, 3301 | eBay As was already mentioned, this sort of thing can also be found at on-line hobby/robotic stores (of which there are many). It'll be hard...
