"Should it work?" Probably not... as in all things, how you do it will determine how well it works. Your posting implied that you were considering driving each string of 30 LEDs
in series with a GPIO pin. Putting the LEDs in series is a good idea, but I hope that @Ghanima's answer has convinced you not to spend any time pursuing your idea of driving them with the GPIO pins. That simply will not work very well at all! But on to a proper answer...
Driving 30 LEDs in series is definitely "do-able", but you will need to spend some time and effort designing or selecting an
interface circuit. This
interface circuit will be positioned between your GPIO pin(s), and the series string of LEDs as shown in the schematic below. Its realization may require more than one item of hardware.

Since LEDs are
current driven devices, your
interface should be a current source instead of a voltage source. In other words, it will regulate its current output at a particular value - a specification determined by the LEDs you choose, and the brightness you want. From the LED page on Amazon you referenced, the maximum drive current required is 20 mA, and the maximum forward voltage drop is about 3.5 v. Using Kirchoff's Laws and doing the math yields the following:
- the constant current
interface must source 20 mA
compliance voltage of constant current
interface must be
30 x 3.5 = 105v!
And so that means that a device in this class might be appropriate for the
interface in your project. Since the output voltage exceeds 70v, it also means that you'll need to investigate the rules and regulations pertaining to its deployment.
But your interface design isn't complete yet (assuming you're using a device similar to the one above) as you won't be able to interface this device directly with a Pi Zero's GPIO. Something like a
solid state relay may be required to complete the design of your
Of course this is just a brief outline. It neglects several details, but hopefully gives a fairly thorough answer to your question of "should this work?". Please post any follow up questions here, and good luck with your project.
