LED worklight?

Anybody tried one of these on a stage?

I'd like to get one and try a slip of blue gel in it as well. The ease seems like an advantage. I do suppose they would walk though.

I recently picked up the version with a regular switch at wally world for 3.50. I haven't fiddled with it on stage but can confirm it is HELLA bright in it's natural state. Haven't had it long so cannot speak to longevity.

This might not make sense for everyone, but depending on what your work light scenario is. I have seen people use the Chauvet Dotz Flood with blue gel on it for the side lights and over the stage just having them hung. They do take up circuits and DMX but if you put them on a small board drawing just AC power from a wall it would not interfere with the main system.

We bought a boatload of these. Cheap and bright. Did I say cheap ?

How do you control them Steve?

Paradigm, with Lyntec motorized breakers for on-stage.

I’ve 2 under an FOH catwalk on a D20 dimmer, they are at full in work mode, at 15% in ghost mode and light the pit and audience.

So the Q&A on Amazon says these lights are not dimmable, and the manufacturer website says they are dimmable with the remote. Are you dimming them to 15% from the D20 dimmer, or using the remote?

Like all line voltage LED, even those that’s state dimmable, they usually suck below a certain voltage. At $22 ea. I’m OK currently with trying them out on the D20’s and see how they behave. They don’t come with a remote.

These 2 sit at full in “work” mode, then and when we close, or a timed event happens, Paradigm takes the dimmer to about 15% and it’s now our ghost light. That’s a level and intensity designed to let someone see the theater, not fall off the stage into the house, yet not be bright enough for students to want to use the space after hours.

If I have a problem with the fixture down the road not liking the 15%, I’ll just set up one fixture at full for ghost, then add 2nd for work. Or I’ll just swap for one of the many Q1000’s these are replacing.

If you're concerned about accurate CRI for your painters, the best option I've found is the Altman 3k worklight. It's a bit pricey, but it's the brightest and most color accurate mini-10 replacement we've tested.

I also recommend the OSRAM KREIOS FLx 90W LED. It's half the price of the Altman one, and has 92 CRI (even better than the Altman one which is rated at 90).

Mark, you will be happy to know we are in the process of specifying 27 of the KREIOSs for a black box flood/work light. The architect balked at the Ustellar as 1) There's no warranty information to be found and 2) There's no specification sheet to use in a bid.

I pointed out, tongue-in-cheek, that who cared about a warranty, we could by a LOT of replacements at $22 ea........ but I recommended the OSRAM.

I was an early adopter of the Kreios worklight (60 watts) but not anymore. I had two fail in the last three weeks 7-8 months out of the three-year warranty. Osram says they do not have the parts to fix the 60 watt version. I need to find a cheaper solution.

I've used these, and they work well but I put a diffuser over them if it's pointed at my face.

Edit: I've used them for working, not stage purposes. I believe most white LED's output a lot of blue and orange and not much else. Something to consider if using color filters.

Hi Steve,

I'm not sure what you mean by, "There's no specification sheet to use in a bid". The Product sheet is available for download on our website and on our E-catalog. Both the product sheet and the manual (both of which can be downloaded from our e-catalog) list the warranty.

Below is the direct link, but if you go to www.osram.us and click on the product information box to get to our e-catalog, you can find it. You can also get there directly by going to www.osram.us/Kreios

I'm happy to hear you asked for the KREIOS, but surprised you had such a hard time finding the data. Please give me a hollar if you have any future issues in finding stuff as I'm happy to assist.

^^^^^^^
Hah, there's more than one reason you should "Read it again before you send!"
Mark, re-read @SteveB 's second sentence, he was referring to the really cheap option.

Amd Mark - those links don't work for me. I think you must have been logged into your account.

Bill,
No, apparently the product catalog session "expires". Not sure why that is.

John D.-- opps. *laugh* yup, I get an F for reading comprehension on that one.

The more time I spend at my day job that has switched out all the track lighting to be the $4 LED home depot special from home depot, makes me realize how important quality light is.
We commonly need to take a photo of a product against a white background for digital reference and working in a 100% LED environment does crazy things to the iPhone camera.

Thinking about theatre and the number of times we had scenic painters that only worked in the middle of the night (because they were servers or bartenders or something) and their only instruction came from the set designer's photos, having a quick photo with horrible color accuracy because the work lights were low CRI would have been devastating.

I have 12 of the early 60 watt version (2012?) and had one fail within the 3yr warranty (np with getting replacement) but that was my night light so it had plenty of hours. Now I have been having to replace the driver/ballast on many of the remaining out of warranty units. Not sure how long they will last.
Just did a google search on the old driver part number that I found on its sticker. About $35. I’m not in the House much these days but will try to track down a p# if I remember. (Big IF)
Still happy with the units but there seem to be many high bay LEDs on the market at competitive price points. Making a complete swap out just as cost effective as a repair.
