These 3W LED chips from TOPXCDZ are pretty good for the price, but I had some trouble getting the voltage right at first. They work fine now, but I feel like the output brightness (260-280lm) could be a bit higher. Not bad for DIY, though!

Great LED chips for my DIY projects
I bought these TOPXCDZ LED COB lamp chips for a custom floodlight I was building, and they work like a charm. The cold white light is bright enough to illuminate my backyard at night. Just make sure you have the right voltage setup, as they need a DC input of 3-6V for optimal performance!

Not as bright as expected
I was a bit disappointed with these LED chips from TOPXCDZ. They provide cold white light, but the 260-280lm output didn’t meet my needs for a larger area. Installation was straightforward, but I wish they had more punch. I might look for stronger options next time.
