My pool builder is offering me standard white light (I assume 120v halogen) or colorlogic LED for a significant up charge. I have no needs for colored lights, but I would prefer LED. Should I ask for a low voltage white LED light (if so any models?) or should I just slap an LED bulb into whatever standard light fixture he installs.
If I go low voltage white LED should there be a price premium over standard 120v enclosure (other than the price of the bulb)?
How big is your pool? Pentair gave me a calc to shoot for 4 lumens per sq ft of pool surface. So that is part of what you need to think about. A joonbug99 mentioned - the led color lights tend to put off a lot less lumens then other white lights.
Check out the chart below for lumen output. You can pretty quickly see that one color LED light does not equal one white LED lght and certainly doesn't equate to one halogen light. This table shows why so many are disappointed with LED light output.
That said - if you plan to use a traditional light - get one that is easily serviceable - and you could try putting in LED bulbs to see if it does what your want. You might want to plan for more than one if you are going to LED.
Remember the calculation - pool area in square feet times 4 lumens.
Average pool - 400 sqft 400sqft * 4 lumens = 1600
This means you would need more than 2 of any of Pentair RGB LED lights.
But since you want a white light - I think you could shoot for one of the Intellibrite 5G Pool lights non RGB lights they would be bright enough for the average pool. If you have a larger pool then make sure you size accordingly.
For the low voltage lights - there is extra cost in the form of a 12v transformer that isn't there in a traditional 120v niche. So that adds to cost as well as the bulb.
Personally - I think you would be fine with a traditional light niche with a standard 120v bulb if you don't want all the colors that the LED offers. Just be sure to think about light output if you are planning LED in the future.
