Way i see it is they are so cheap they have to be worth a try and with the blue/white light extending your day things shouldn’t stretch too much. Have a hunt around pal, i knew about these things cos i have a womble friend who’s got greenhouses and was not looking to spend much as usual so i kind of found them for him as a bit of a joke really. Thing is he’s not laughing, he thinks they are a great idea. They aint much money down the drain if they don’t work well cos you connect them straight to your 12V battery with no hassle over drivers etc. Oh and they are water proof to a degree which other types wont be unless you spend over 1000 dollars on a professional horticulture led bar or similar which needs your inverter to run it
You could get a couple to try for the price of a decent pizza here and if they work ok get some more
