LED light stripes for supplemental lighting?

[dipoledipole]

Hello magical people of Growing Under Lights! super noob here, I was wondering what is the possibility of using LED stripes to provide supplemental lighting during the winter on a windowsill?

I saw a tutorial on instructables
that uses LED light stripes as grow lights for air plants.
The tutorial seem to be written by a manufacturer of LED lights, and in the comment section, they claimed that the LED provides the right spectrum for plant growth......(I have my doubt)

putting that aside, I found a cheap version on Amazon, it says the following in the description

* LED Quantity/Type: 300xSMD3528
* Input Voltage: 12VDC
* Power: 24W
* Beam Angle: 120°
* Available Colors: Available Light Colors: White (5000-6500K)
* Light Output (lumen): 900-1100
* CRI: 70
* Operating Temperature: -25～60ºC
* Strip Width: 8mm
* Length: 16.4ft (5m)
* PCB Color: Copper
* IP Rating: IP33

Ignoring the fact it did not list the spectrum measurements, if the light output is 1000 lumens, and let's say I'm only using it to light up a square meter of space, does that equal to 1000 lux?

If I'm aiming to light up 1 m sq. of space with 1000 fc (10,000 lux?) of light, does that mean I will need 10 of the 1 meter LED light strips to fill up the 1 m sq. of space?

please excuse my ignorance if my questions are stupid...

------------------
For reference, I live in zone 7b, on the shortest day of the year I get around 9 hours of sun. I grow a wide light range from Catts to Paphs on both the western windowsills and a bay window that gets light exposure from the north and the west. To be honest, I can deal with my plant slowing down its growth, but I would really love to figure out if I can add in some supplemental light without costing an arm and leg

Those LED lights don't look like they will give you much light for the price. I have my plants in a North window and added grow lights from Walmart for about the same price as one strip. I took the plastic covers off and hung them. They don't really get hot either.

I looked up a few of the specification categories with which I wasn't familiar.

SMD3528
Each LED in the strip is 35mm x 28mm

CRI
Color rendering index. The degree to which the color of objects viewed under a given lamp appears compared to the same object viewed under an incandescent lamp. CRI of an incandescent lamp = 100(%.) This would have no bearing on plants since it relates to the light reflected off the object, not the light absorbed by the object. These lamps at CRI 70 would make red objects look different.

IP33
IP33 appears to mean the LED enclosure on the strip is not waterproof. IP55, IP65 and IP68 are waterproof.

I don't know that there's enough information to judge the particular light you mentioned as far as growing plants.
