Review: very good power supply , i put outside but with aluminum cage and works excellent - very good power supply , i put outside but with aluminum cage and works excellent , i will keeping buying this power supply , no problems , i like it
Review: Good but has a loud fan - I’m using it to power four 20” light bars. I only had to daisy chain two of the lights together because the driver has connections for only three lights. Works fine so far. I haven’t had it long and it hasn’t rained yet. Fans is a bit loud. If you want something quiet then this is not the driver you want

### ⭐⭐⭐⭐ Good but has a loud fan
*by C***. on September 26, 2020*

I’m using it to power four 20” light bars. I only had to daisy chain two of the lights together because the driver has connections for only three lights. Works fine so far. I haven’t had it long and it hasn’t rained yet. Fans is a bit loud. If you want something quiet then this is not the driver you want

### ⭐⭐⭐⭐⭐ Weather resistant
*by G***H on July 17, 2019*

Paired this with orange LED light strips on our patio's sunburst. The fact that it is weather resistant is what made me decide to purchase it. The constantly ON fan is a bit loud, but it's not an issue for me since i mounted it on one of the rafters which is about 12ft overhead. I recommend this PSU.
