When you say led tape you mean the roll of LEDs with a sticky back? If so I tried it a year or 2 ago using the smd 5050 strips and they were good for low light plants but most of my higher demand plants lived but they had very small leaves and didn't look all that healthy. They now have more powerful led strips like the smd 5630 and 7020 which are a good bit more powerful. I would recommend trying those if you continue this route. Here is a nice comparison video with par amounts.
