If possible, please provide brand(s). Thanks!
By the time you find them and realize the extra expense you can find some Low voltage ones that will give a better quality of light in both quantity (more light out-put) and quality (better color). Halogen bulbs produce the best kind of light, It’s a whiter light than xenon or incandescent. Many of the landscape light fixtures (low Voltage) use halogen bulbs. Find a price range and take the time to do it right or spend your money on the cheap solar and after they break then buy the better kind. The most common thing I see is people will buy a low voltage system after they realize the solar ones don’t work, it’s a waist of money in my eyes.
