Mean Well HLG-185H-C1400B Power Supply, Single Output, LED, 200 W, 1.5" H x 2.7" W x 9" L

Used this in a 400W LED light fixture and it has given me years of trouble free use. Wired up a pot to dim the light fixture as well with the supplied dimming wiring option. Cant ask for a better product! All described power ratings from manufacturer are totally accurate. I would definitely recommend this for anyone looking to DIY light build or even to replace an old ballast in a fixture worth fixing with high quality components. A true 5 star product!

Mean well = your safety. I own 3 of this setup to various Cobs and pucks, and a multitude of other Mean wells. Work like a charm and last years. I have Mean wells still running over 15 years on continuous cycles.

Be aware that this is a constant current power supply and not a constant voltage power supply. I did not realize this when I ordered it and I didn't know what to do with it since I am used to working with constant voltage power supplies. It turned out that it was exactly what I needed. My lights are wired in series and this power supply provides the constant current they need for full potential lighting.

Very well built, reliable, and perform as they should. I've used these a few times to power citizen clu-048 1212 cob chips with passive cooling while pushing each chip @50w. Would not hesitate to purchase again.

My husband bought these for a project he was working on, and was very pleased with them! We are re-doing our house and were making our own lighting system.

Great product. Mean well is always the best choice for these drivers, especially if you're building cob arrays.Lowest price I could find and shipping was fast.

Great quality drivers only one I will use for my builds of leds. ..

I got this power supply for cob LEDs and it works perfect
