First off, thanks so much for this forum. I purchased a house with a pool a couple years back, and knew nothing about pool ownership/maintenance. this forum has been a life-saver, and although I haven't posted previously, I've lurked around gaining info for years.
Anyway, my questions for today is about Color LED Light Upgrade options for my pool. I've assessed that I have Pentair/Amerlite niches with 120v Edison screw-in bulbs in them. Of the three lights in the pool, the one I'm looking to replace first is the 500w in the deep-end as it's burned out. Provided that goes well, I'll end up replacing the other two fixtures in the shallow end as well. It appears that my options for plug/play screw in Edison bulbs to fit my current fixtures are:
1.) Pentair AmerBrite Color LED Replacement Lamp - 120v 
2.) J&J ColorSplash 2G or 3G Bulb
3.) Random SMD LED and LED bulbs of unknown origin off Amazon/Ebay
I've read a couple reviews of the ColorSplash both here and on other sites, but really haven't seen any reviews of the AmerBrite Color LED replacements. Was wondering if anyone had these in their pools and what their thoughts were on them. Extra Bonus Points if you've had or seen both the ColorSplash and the AmerBrite and could compare the two.
Finally, while not off the table completely, I would like to avoid having to replace the whole fixture with something like an Intellibrite system is possible, as I don't particularly trust the pool contractor that built the pool based on other finders over the last couple years, and I'm concerned that I might run into troubles fishing the approximately 400' of combined umbilical cord from the three fixtures. That said, does anyone know of any major advantages of going with a whole new fixture as opposed to just using a new LED bulb in my current fixture? They would certainly have to be compelling to justify the added expense/effort.
Again, thank you all so much.
