Lemax Light power question...

You can adjust the voltage down from your source to suit your taste. Depending on the “total” number of leds powered by the buck converter(step down module), most modules can handle up to 3A each. Here is a picture of one and an item number to put in ebay search as an example, but you will find them cheaper and free shipping by searching around. So, you probably won’t need one per skid.  Maybe just power a buss or teminal strip with one.  Although, they are cheap so I buy a dozen or so to have them on hand.  Some convert ac to dc(xfrmer power) and then step down for slightly more money, or, use your dc to dc step down power supply.  Hope this helps.  Item number 251066005460

Here’s a photo to make you laugh.  This is xfrmr acc power converted to dcv to power a terminal strip.  Some dcv leads go out at 10vdc to accessories, and one lead goes to another dc to dc step down to power a lemax xmas tree at 4.5vdc.  I know it looks like a mess but sure works well! 

Thanks for the info- I was looking at 1 per skid just to make wiring easier. 
Is there any life extension on the bulbs at 3vdc? I don't want to go to the hassle just to have bulbs burn out after a couple operating cycles. I believe they are grain of wheat, not LED- I could be wrong though...

The “real” electrical types should weigh in here, but it is my understanding that generally lower voltage extends life.  But there may be current issues that I’m unaware of.  My experience with these street lights at 10vdc to tone them down in brightness has been just fine.  No problem.

 This is 12vac from acc side of transformer that I thought was too bright.
