They would work somewhat, but not really the right tool for the job, so to speak. These are designed to give human eyes a view similar to noontime sunlight, but the spectrum that optimizes plant or algae growth is actually in 2 narrow bands. The bulbs that work best for that, depending on which technology you decide to use, are either very bright and produce immense heat (metal halide- great, but not efficient, hence, energy wasted as heat and all the unnecessary wavelengths that make it look sunny); a little more efficient, but cost more for bulbs and ballasts that produce the same amount of useable light (fluorescents of different varieties), or LEDs, which are the absolute cheapest and most efficient, but look bluish or reddish or purplish when made as grow lights, because LED technology allows specific spectrums, and make it easier to just produce the wavelengths of light needed to grow plants, even if they look wierd (or neato) to the human eye.
These are good for garages, shop lights, work lights. Your houseplants won't mind them, and they'll look pretty, but they won't actually grow that much or that fast, compared to actual grow lights.

They would be decent for supplemental light on overcast days if you have a light dep or greenhouse set up. But these can not be used for full indoor grow

They are surprisingly good for such a cheap price. They are lightweight - it's just a pair of thin walled tubes and they seem like they could get damaged if handled roughly. Each light (pair of tubes) is wired individually, so they can be installed to 4 seperate locations. Each light has a 2 prong outlet on the end to daisy chain another light. The light itself is decent, but not spectacular - the temp. is around 5000k and it's well diffused in all directions (including up, so a light colored ceiling helps). There's also a hardwired switch on the plug end of the wire. The claim of 4000 lumens per light seems way off base, it's more like 1000-1500. It comes with some lightweight chain for hanging as well as some little clips for flush mounting against the wall. For flush mounting, there are also slots in the back of the light to hold the head of a screw. These aren't some elegant light for the living room or kitchen, but for a garage or unfinished basement, they work well. FWIW, each light does have a sticker with ELT and Intertek.
Look at the Camelizer.
