Great RGB Leds. Bright and powerful

Worked perfectly. Used it in a project I had for my 50 in tv along with a Raspberry Pie, hyperion software to make the background color match whats on the screen of the tv. After spending about a $130 and getting all the hardware to talk to the software, I got them to work perfectly. The lights are bright and responsive. Very customizable and easy to work with. Great LEDS for those projects that you will love to tackle.

For the price this is the best deal you can get with an RGBW LED Par. Each bulb is quad LED which provides smooth color mixing and different pastel colors with different color temperatures of white (as opposed to a "cool white" you get with RGB pars that have a slight blue tint to them). You can also pull off a decent amber color that comes close to the amber LED pars, however I wouldn't recommend these for clients looking for amber if you plan on using these for up-lighting. Will definitely be buying at least 3 more to add to our arsenal. The bracket does feel a bit flimsy compared to the metal ones provided with American DJ or Chauvet fixtures and the fan on these might be a bit noisy for quiet situations, but not a huge deal since again, for the price these are great!

Very very bright. Very well made.
I've had HID and Halogen, these LEDs are by far the best and brightest I've ever used.

Fits perfectly. Bright led's. What more could you want?

Really bright LED's. Ordered them for my Harley to light up the plate, and I was very happy at how much light these give off. Will buy more for my truck.

Excellent bright lights.  Installs just like a standard fluorescent tube.  Plug and play.  Color was whiter than a standard fluorescent which was fine.  Using mine in a 55 gallon fish tank.

These are very bright LEDs and the color range is just as good as I expected. One thing I will note for other customers is because these LEDs are clear, the colors don't really "mix" you will have to diffuse them somehow if you want your project to appear as if it has one LED capable of generating many colors otherwise you can clearly see the beam of light from each individual color chip. If I were to buy again, I would probably look for diffused RGB LEDs. As a quick fix, I put a frosted finish on a few of them using some 120 grit sandpaper and that worked just fine. The front of the package indicates that the longest lead is GND, and even specifies the voltage to each positive lead. Red doesn't require as much power, so you'll have to give it a higher value resistor than blue and green. All parts arrive in a small plastic bag but surprisingly, I didn't find any bent leads. It would have been nice to only have to purchase 20 or 30 since I only had one project in mind for these, but the rest go in my parts bins for next time and it's okay to have extra stock.

I didn't buy these on Amazon but on another website because they were slightly cheaper. The bulbs work very well. Brightness and color (2700k) are very nice. I have some other, more expensive LED bulbs like these and they seem very comparable. I would get these again if I needed more and if they last.

Probably one of the best RGB lamps on the market. Great build quality and the white light provides ample amount of brightness for any office or room. The RGB lights are great for setting an ambiance and are quality.

work well, pretty bright led flood replacement

They are very bright, too bright to stare so maybe 200 watts. Love the LED Blue/White so much better than incandescent or halogen. No heat, low power use.

I ordered these and I also have the previous generation of this LED. They managed to cram an additional column of LEDs in the center on both sides. That is about the only change I can see when looking at them side by side - the components on the board appear to be the same. The previous generation was already crazy bright and this just takes it up to 11. These LEDs are several times brighter than your old incandescent bulbs. They are extremely impressive.

I was putting the new LEDs in one reverse housing and the previous generation in the other housing. The obvious observation was that they are really bright and starring at them messes with your vision and causes you to have to wait a few minutes before you change LEDs out to compare the others.

The new generations of both bulbs are indeed brighter and the pictures I took  make it easier to see the difference. You basically get to compare the glare from each housing. In person you can see the difference side by side but its hard to see a difference if you see them on without any comparison. These are excellent LEDs but unless you need the brightest available I wouldn't order these as a replacement if your current previous generation ones are fine. If you don't have the previous generation already then yes - I would order these newer ones.

These LEDs have a t10 base so they will fit into the socket for many applications (168, 192, 194, 912, 921, etc..) and if you have room above the base you can use these there. I have a bunch of 921 LEDs in my 3rd brake light and also in the headlight as a DRL. Even with the headlights on you can easily see the LED above it. They won't fit everywhere though.

My car doesn't have any bulb out warnings or CANBUS but previously with the previous generation bulb when reverse was not selected the LEDs would be dimly lit and would flicker. I installed a resistor to fix it but I also could have just wired in a small incandescent 192 bulb. Evidently even when they are off there is still a little bit of voltage getting to the LEDs. It was never a problem with incandescent bulbs but the LEDs can lightly glow with small amounts of power. I happened to have some resistors or I would have just used a 192 in a socket behind the light. Either way works.

I received these for free for the purposes of reviewing and evaluating in an honest and unbiased manner.

Great bright led light, the color temp is just a little more blue than I would like 6500k, but
It's not a deal breaker. Stays on all night with full sun exposure during the day

Wow these things are bright. My other t10 bulbs were a little too big and was hitting my map lens on my car. I had a t10 with 20 2835 smd and these 5730 was twice as bright. In the picture the old t10 2835 are on the left and the new t10 5730 are on the right.

Great lights and great replacement for higher wattage lights.  Produces an all around light.

I changed all of my lights to LEDs recently.  I couldn't be happier.  They are bright, cool to the touch, lower energy usage.

LEDs are bright. The fans also move a lot of air around too. Using one for intake and one for exhaust. I plan on getting a couple more to finish out my build!
