  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Group Buy: Budget CRI 95 LED Strip Lights

Brandon,

the color degree knob and the printing on it looks a little broad. Warm-Cold with some generic markers isn't what I would personally choose and leaves it open to user error. The Actual Color Temperature on there could work, but an digital display would be the best option.

if not possible, could the digital read out be available in the wireless application?

It's meant to be broad and to work with any strip you want to use. Even systems costing thousands don't do what you're asking for. The controller itself has no way to detect the color temp or range of the strip you attach to the unit. I personally have 2,000k - 10,000k, 2700k - 6000k, 3200k - 6000k, 3200k, and 6000k strips. Warm to Cool works for any variable strip I throw at it and it's the standard nomenclature for LED strip lights. It's even what Lite Gear uses. All that said... What you're asking for could easily be added to an iOS or Android app. The WiFi and RF wireless functionality that is built in to these allows for the functionality to be expanded hugely. I think what you're describing will definitely come once these are in the wild.
 
Looking good Brandon Quick questions: are the 4 channels independently dimmable? Will controller accept 24 volt input? (looks like that on label) and would it then output 12volts?

You can use a 24V input, but that's what the output will be, so you will want to stick to 12V.

Single channel control was never part of the original spec, but... stay tuned.

just seems like if you're using a variable strip it could be open to human error if the dial is moved between shots, where a digital setting wouldn't be.

can the controller be calibrated to the strips and have the temperature stenciled on the dial?

Everything we do in those business is open to human error. Personally, I use a color spectrometer, but most people don't and get by fine. You also seem to be assuming other types of lights we use are the correct color temp. Since I've gotten my color spectrometer I've been testing everything I can get my hands on and have found a lot of variance. Especially with Kino Flos and HMIs. They can be off by a shocking amount.

kinda have a feeling I could make marks myself for variable strips, but seems like they could make it more exact. Shouldn't all the variable strips be the same and easy to make some broad marks on the controllers to get us close to 3200,5600, 6000?

It's really not difficult. Turn the knob all the way to the right for 6,000k, all the way you the left for 2,700k, and 1 notch up for 3200k. All the variable strips in the group buy are there same, but you're not locked in to using only strips from this group buy. That's a good thing.

I am only using a color spectrometer when I'm trying to match the strip color to a specific non-standard color temperature. That's fairly rare.
 
So what's our time frame on this shipping now?

The manufacturer is on holiday another week and I'm still testing (all good so far), but based on our previous conversations, late March is possible, but likely the first week of April.

Going to bring them to NAB and get a booth?

It would be the first Group Buy booth ever :) That's definitely not happening, but I would like to bring a few of these to NAB to show people. It would also be cool to meet you guys in person. I'll try to make it happen.
 
FLicker question: I took an old strobe beauty dish and taped 6 strips of 6" daylight leds. It kind of looks like the top of a CharBroil BBQ grill - we call it the BBQ light. Anyhow - it was to be our source light and after powering it up we noticed a slight flicker. I tried 2 ac power supplies and a 12V battery and still saw a flicker. I put a meter on it and the meter swung 1/10th of a stop back and forth. We pulled the light and went to a kino. Is this normal? Are the controllers being built to take care of this? Thanks.

What you are describing sounds like an electrical problem. It sounds like one of the solder joints got loose on the strip. That's happened to me once before. It also could be a problem with the wire you are using between the strip and power source or it could be shorting out on the metal (I assume) beauty dish. Do you have a voltmeter? You could use that to pinpoint where in the strip there is a problem and resolder it or just snip that piece out, if it's bad. It's definitely electrical.

LED flicker is not actual flickering. It's constant, and looks like this:

If you are not dimming the lights at all (full power), there would be no flicker even at 1000fps (tested), probably even higher than that.
 
I have 2 controllers extra bought and paid for if anyone wants in on them and need 2 strings of variable
