They are pricey, but a lot of people love them, including me! You can’t argue with their results, and you can go with shorter versions than the length of uvb you need, plus they link to the uvb fixture, so you’ll have two fixture on only one plug! Now, my jungle dawn did just sort of half die (half of it is lit up like normal and half is flickering- it used to fully flicker in the past but I’d just re plug it in, give it a gentle love slap, etc before to fix it). Now is it the fixture itself or my fault for accidentally occasionally spraying it with water when hand misting? I’m guessing it’s me, but it hasn’t been an overwhelming amount of water, so who knows. If you’re willing to spend the money, I do recommend them! If you want a stronger plant bulb in your current dome fixture, Sansi bulbs are great, as well! When you buy a basic fixture, it comes with a 6400/6500K daylight bulb, which doesn’t need to be replaced like a uvb bulb, as when it dies, you can actually tell because it’ll stop lighting up (unlike a uvb bulb), those are cheaper and still work, but they don’t put out as much light as the other options. Other places do make their own version of jungle dawns, too, though I’m not sure on the prices compared to Arcadia or how well they work, as I’ve never used them. Whatever you choose, make sure it is white light only, not blue and red and white LEDs lighting up in their respective colors together
