The solar spot lights I have now are very dull and don’t last very long. I want ones that can light up a tree and can stay lit for at least 4 hours.
I searched from the Internet about the solar spotlight purchased by my Uncle
for me, which specifications you will find below. It works very nicely for my use:
Integral Solar Spotlight
Three-light solar set with LED lighting
One day of solar charging powers three LED bulbs
Spotlights last for up to 10 hours
Include an automatic on/off sensor
Saves you money on your electric bill
Comes complete with ground stakes, bulbs, and a 20 foot cord
Highlight the best features of your garden or yard with this Solar Spotlight Set. After a day’s solar charging, its long-life, rechargeable batteries power three white LEDs, which emit a bright, white light to accentuate your plants or outdoor decor for 8 to 10 hours.
These lights feature a durable polymer construction in an attractive black finish. The three spot lights are connected to an integral solar panel that charges all three lights. They also have an automatic on/off sensor so you don’t have to bother with elaborate timers. This set of hassle-free, energy-efficient lights will also save you a considerable amount on your monthly electricity bills.
