Newb, just joined... searched a bit, tidbits here and there- but thought I would put it in a new thread.
Old Fiberstars fiberoptic light- one fiber they split into two bundles, ran to two separate lenses pointed towards each end of the pool. Never had enough light- shallow end barely OK, deep end murky. About 18 years old, removed the light and fiber 4 years ago.
Has the threaded lense housing flush with the wall. Looks like 1.5" will go 8.75 inches into the hole.
I am planning on installing an LED light, actually two, into the existing 2" threaded fittings.
1. Can the light be replace WITHOUT dropping the pool level? Cannot see draining 600 cuft of water here given water situation AND im on a well. I could build a caisson to let me create a water free volume around the lens. an 18x18x18 plywood box, sealed, foam to seal against the wall- just suck all the water out....
2. Options for 'nicheless' seem to be:
Jandy 9, 20 and 30W
Savi/Melody (seems like this is the Jandy, I thought I read Jandy bought them) same wattage
Any other vendors am I missing?
(Might I add the darn things seem way more expensive than they should be... )
3. There seems to be little data on brightness of any light, nor any real comparisons. Any good resources? Or real world experiences?? One vendor says "will illumonate 200 sqft of a light pool".. wow, talk about a weak spec...
4. Will a 5W be adequate? Will a 9W be adequate? or do I really need a 20W?? Or 9W in the shallow end, 20W in teh deep? If I do a 9/20 can the brghtness be adjusted to create uniform brightness? (yes, my hole is 8.75 but the spec says 9.00. I am *hoping* the 1/4 inch wont matteras there is a 1" conduit that contines in line with the initial 8.75" segment.)
Oh about 30K gallons, irregular, but 32 ft by 18ft. Shallow end is 4 ft deep, 9ft at deep end. 20ft 'disappearing edge' along shallow end. The lights are mid pool, a round planter kind of sits in a 'kidney' point, so two lens point towards opposite ends. Like \ /.. well, more like 90 degrees betweeh the legs of the V.,
Sorry for the long post and lots of Qs.
Appreciate any inputs!
