Does what it’s supposed to do

Purchased for my Nan..She loved her flowers and plants and I  bought this product for her because she said she needed to give them extra support especially where her bungalow is situated as most of the day there is just not enough sunlight.The lamp works perfect,It’s tiny but powerful. easy to use, simple to clip on and adjust as gooseneck design, timer can be set as can the brightness , can see difference in plants in the few weeks she had had it.They got so healthy looking. She was so pleased ... results achieved... would recommend mend
