You will need to use an LED driver capable of 12V DC and most landscape lighting transformers are 12v AC. You can use an AC to DC converter as an alternative option. That said, what size is the gazebo? 24vdc is probably a better option for tape light as 12vdc is limited to about 16.5ft where 24vdc can hit around 60ft for a 1.5w/ft tape from a single side injection (if this is over your head no worries, ask away) And now the honesty moment : for the sake of ease, in a DIY environment. Just go with outdoor string lights. Everyone loves them in exterior environments and they weather better. Get the ones with replaceable Edison type bulbs and pick up 2200k, 2400k or 2700k bulbs for them (lowest watt you see available to you). Put them on an ELV+ dimmer with a neutral and you will be more than thrilled. Hope that helps. More on reddit.com

I like the BTF-Lighting WS2815, these need 12V and offers a second datasignal line as a backup If even illumination (edit: and high brightness levels) is an important factor for you, I recommend you to power inject around every 20 feet (around every 5 to 6 meters), the voltage drop across the small and thin copper traces is quite large More on reddit.com

Short answer: 24v. Long answer: It depends on your project + led strips you're going for: Power requirement (watt/meter or per led) + LEDs per meter Digital or analog Length 24v: For analog, this is pretty much the go-to. It's just easier to manage voltage drop with 24v especially if you need to power multiple strips. For digital, 24v is nice but the leds are usually addressable per group of 6. 12v: Easier access to power supply and controllers. A bit more planning is required for longer strips due to voltage drop. More on reddit.com

I recommend led strips. They come warm (3500⁰ K) and are great for tucking away so the light is ambient and the light source never hits your eye. They only draw about 24 watts. They run on USB so there's that but they come with a remote. More on reddit.com
