Extremely handy and fairly affordable, the best solar post cap lights also have the advantage of being quite eco-friendly, which will help you cut back on electricity bills. However, because of the varying kinds of models- not to mention price tags- choosing the best solar post cap lights can be tricky, especially if you’ve never bought one before.

Here are a few tips to get you started.

UPDATE May 2019: The popular and top-rated Westinghouse models are currently on sale. The deal may expire at any time, you can check out the bargain here.

What should you take into consideration

  • Hours of illumination: The first thing that you should consider is the usage you will derive from the lamp: 6 hours? 8 hours or longer? It’s quite important to consider how many hours of illumination you’ll need per day since some lamps are specially conceived to sustain long-term use, but bear in mind that these can be more expensive.
  • Material and build: If you’re planning on using your lamp long-term, you do need one that will sustain its share of wear and tear. Cheaper models are made of plastic but if you can afford to splurge, it’s worth investing in a stainless steel one. Be wary of cheap imitations though- some lamps may present a metal-like exterior but inside, they’re made of reinforced plastic.
  • Budget: If you’re on a limited budget, you can also look for lamps powered by Lithium or NiMH batteries. Long-lasting, these lamps also have the advantage of being able to sustain extreme weather conditions. NiMH batteries are quite budget-friendly and can last for several years.

With that in mind, here are some of the best solar post cap lights on the market.
