Pentair 620425 MicroBrite 14 Watt Color LED In Ground Swimming Pool and Hot Tub Spa Underwater Light with 100 Foot Cord

Used a $25 adaptor off Amazon and this light to replace a globrite - works great so far fingers crossed it holds up longer than the globrite.

Back in 2014 we installed an inground fibreglass pool and illuminated it with Pentair GloBrites. The vibrant colour from these LEDs highlights the glass resin and creates a magical scene. Unfortunately, the product themselves are prone to a high failure rate. As of 2025, we have gone through 3 sets at over $1500 per set. The first set was covered under warranty, unfortunately the next sets weren’t. I’m also fortunate that I can change the lights myself so we’re able to save on labour but it is still a huge investment for 2 lights. This spring we unwrapped the pool after its winter slumber and found that another GloBrite had failed. Shocked? No. Disappointed, yes. I researched replacements and have heard relatively good things about the Pentair MicroBrites. I purchased two new MicroBrites as well as the corresponding adapters to fit MicroBrites in to a GloBrite housing. The parts are: “Pentair Adapter Microbrite To Globrite – 618040” and “Pentair EC-620425 MicroBrite Color LED Light 100′”. For anyone worried if there’s a noticeable difference if you mix-and-match the GloBrites with the MicroBrites, there isn’t. Physically the lights are smaller and the power cable is thinner, but the output matches the GloBrites. I took this picture to show the similarities between the two when using a fixed colour. I did not run a colour-swim.

Pésima calidad y durabilidad. Menos de 1 año y ya dejó de funcionar… NO COMPREN!!!

I spent $600 for this high end led light. Lasted 1 year!!! Wast of money. Thought I bought the warranty but I messed up. Amazon should not sell bad items like this. The warranty was for 30 days. I am very disappointed in this pool light. Item was professionally installed as per the directions. Poor quality. This was a terrible value and again disappointed in the $600 spent. Pentair LED pool lights are trash and expensive trash at that.

I bought this light and a Microbrite to Globrite adapter for my pool. My burned out Pentair Globrite light lasted 3 years ... not happy. Anyway the Microbrite is supposed to be improved. It's smaller and requires an adapter. Sounds easy. What I thought would be easy turned out to be a little more complex. The 1.5" threaded adapter ring (The white donut under the light face in the picture) was G L U E D on the light out of the box. It is not required for the replacement I was doing, only if you want to spin the light in a 1.5" female pool niche. The instructions show the 1.5" threaded ring to be separate and can be installed with an o-ring for a sealed conduit if needed. I had to use a dremmel tool to carefully cut thru the ring in 3 places and remove chunks with pliers. I dressed the light body to remove old glue and slipped my Globrite adapter on with no problems. Getting the ring off was a pain. Why they glued it on when they show it as a seperate part to be used if needed is beyond me. Next review will be about the light longevity.
