I have plenty of garden lights and my plants have never been affected.

I, too, have many solar garden lights and have seen no ill effects on my plants. I will say, however, that some plants require a certain number of hours of darkness to trigger their blooming cycle, as is the case with Poinsettia, Christmas cactus, and other light-sensitive plants that may well be affected by the extended hours of light and result in the lack or diminishing of blooms.

Great. DH thought maybe so thought it would a good idea to ask the experts. Thanks

Some solar lights just give off enough light that looks like a night of full or almost full moon, and only for that one spot, not your entire garden.

That is still considered night time to the plants, so your lights may be fine in the garden.
