I know these are technically spot-lights, but they work great as stage-lights. I set these up 70' away from a 8'x18' stage and they work great. I plan to get 2 more soon.

Good brightness framing shutters not have a sharp edge when using Gobo. Go Bose will not have a sharp focus with these plastic optics

These are great! Cost, WOW! Brightness, WOW!. Ease of use and function, WOW!.
Seriously, we have been searching, for a couple years, for the best Zoom Leko for the lowest price and this is it. After a small test order we quickly found that these are, hands down, a better tool for our rental stock for these reasons:
1. these run on 180watts of power. i.e. 8-9 units + on a single circuit!
2. these are brighter than our ETC source four jr. 575watt lekos.
3. these don't have an exterior heat sink. The chassis is cool to touch when on and can be focused without burning your hands. YEAH! Finally.
Yes, the lens is a lenticular "plastic" lens. this helps keep the weight down.
Yes, this unit is BRIGHTER than our 575watt HPL lamps
NO, you wont burn your hands trying to focus it. The LED engine and power supply are housed inside the a metal chassis that is fan cooled and doesn't get too hot to touch.
The control is easy via the on board buttons for manual use or DMX addressing. Simple stand alone use!
The color RGBW feature is awesome and compared to our Source four jr. with a red gel, these are hands down, brighter and smoother.
Also, this unit has a 3200k preset and it matches very well with the 200watt stage right ellipsoidal.
Conclusion. We converted our rental stock to these. Love 'em. We have sold dozens to a local high school. Very, very satisfied
.
We will be buying more!

Statewide Productions, Ceres, CA

We have purchased both the RGBW and 3200k and love them both!

Own several and expect to be getting more for permanent install

This light is built well and everything on it works correctly. However, I have several 75 watt LED lights that are very much brighter than this light.

For the money, this is a fairly decent light. Other Pro LED ellipsoidals cost upwards of $2000. We purchased several of these lights to replace 750w Halogen ellipsoidals that were being used as back-lights (traiditonally ellipsoidals with red/blue gels) in a church setting. The light output is probably not up to a 750w light, but maybe more around a 575w halogen. For our purpose, that was fine. It is also not a $2K light.

The light being RGBW is nice. Would like to see Amber tossed in there, but knew going it that this does not include that.

The lighting if colors is nice and clean, no artifacting seen when in use (or staring at the stage floor). The zoom and focus features work just fine. You can blur to sharpen as needed. It also comes with manual shutters for all four sides of the light, and work well.

The light is all metal, and feels decent (sort of heavy as well, surprisingly). The light does have a mount bar, and it is decent, does not bend or warp. We use stage C/pole Clamps and the threading is very tight with the existing hole in the bar. While I did get it "threaded" through the hole, probably would not hurt to drill it out slightly if using a lot of clamps like this.

The unit accepts a POwerCON connector in-and-out. Very nice for daisy chaining power. The power cord comes with a powerCON on one end (blue), and traditional plug (NEMA 5-15) on the other. The light kit comes with the gray PowerCON that you can cut off the traidional plug end and, replace with the gray connector. Keep in mind however, the power cord is failrly short 3 or 4 feet. I purchased same/similar cords on here (At Monoprice) that were 10 feet and 20 feet long. Same thing I needed to cut off the plug end, put the aforementioned Gray plug end onto the cord, and move on. The manual mentions this, and gives a diagram, but it was a but confusing (Google is your friend).

Menu setup for DMX, Master/slave, etc is done via the backlight LCD screen. Nothing of unusual note here, standard setup. There is only a nine channel mode. While fine for us, might be of concern for those with limited boards (8-channel sloution would have been nice).

Packaging of the light was a sturdy box. While you could use it for mobile purposes (road trips), you will want a travel case if you do that a lot.

While I liked everything about the light, and generally happy with it, I had one minor issue. One of the three lights purchased failed in three weeks (unit basically went all white output and did nothing more). Like others has mentioned, my guess would be the unit overheated and the fan failed. I did not spend the time to trouble-shoot to confirm, just sent it back, RMA process was painless. Got a new unit a few weeks later.

The units are only used on Wednesday evenings and Sunday mornings, so not constantly on. The fan, however, stays on 7x24 (should be thermal instead). The fan is not loud, so no impact thre. The failure of the unit itself, and the constant fan, the product looses one star.

The Stage Right 180W COB LED Ellipsoidal is all in all a pretty good light (Can't beat the price for an RGBW Ellipsoidal). The fan on the one I received is quite and I have not had a problem with the light over heating. Focus and zoom are good but does have some soft edges. The one draw back I have is the brightness output of it. Could be the plastic lenses that are blocking the light output a bit. I have a 140 watt Moving Head LED that is brighter on stage than this 180Watt LED but to fair the Moving Head is a single white 140watt LED with a color wheel and not the COB design this light has. I would recommend this light but just a heads up that it is not as bright as you think it would be.

We have a closed ceiling with openings, I'm planning on using these as back light for our musicians and pastor. I tested these on a road trip in a hot gym in Colorado with high school students. They didn't overheat and survived the road trip.

For the money this light is a winner. However, there are some gotchas. 1. The light overheats. That could be because of a failed internal fan, or just because it gets hot. I solved this problem by getting 2 USB 8" computer fans and strapping them to the top and bottom of the air intake / output with zip ties. No more overheating. 2. The main dimmer channel is 9. So on a DMX board with 16 channels it is the first of the B channels. No matter how you turn on the RGBW, if you don't have 9 up you won't see anything. I spent 2 hours with tech support and they couldn't solve that one for me, pure trial and error got the job done. But for the money you would be spending $3000+ to get the same features in the light.

Features wise, this thing has it all. We are a small professional production company and decided to try a pair of these. The first 2 came and one unit had a bad fan, but Monoprice's stellar service dept. replaced it right away and the replacement is in perfect working order. I gave this 4 stars instead of 5 only because (a) 50% failure rate when it's brand new is not a good sign and (b) slave mode requires the use of DMX Channel 1, rather than having a dedicated master/slave mode. Other than those 2 things, I would give every aspect of this unit 5 stars. Solid, industry standard construction, relatively quiet (you can barely hear the fan in silence), excellent focus, color mixing and dimming curves.
