This light will work with plants but I wouldn't recommend issuing for bearded dragons the uv isn't strong enough

Yes, you sure can. We did. Be prepared to buy more though. They don’t last long. 

I wonder because I heat room for tarantula's anyway could I just use a white or blue bulb and maybe 2 florescent bulbs on each side. It'd gets very hot with 50 watt so stepped down to 25 watt. I cut everything off at night then back on in day. Any recommendations on a 40 gallon

Hi there! As long as there is a sufficient source of heat and UVB, this should be fine.

Hey there! Using a Zilla Mini Heat & UVB Fixture with a Zilla 50W Mini Halogen bulb and a Zilla Tropical Mini Compact Fluorescent UVB Bulb will provide the correct heat and UV for your Corn Snake to thrive.

Hi there! Red Eared Sliders, like many available aquatic turtles found in pet stores, get large and need a lot of room to swim. Reaching upwards of 12", and being very powerful swimmers, causes them to need a very large water source to swim in. For turtles up to 6", a 40BR Aquarium will work, but you'd still want to provide a larger aquarium if possible. By the time they are 10", they should be in something no smaller than a 125 gallon aquarium, and again larger if you're able. Since they eat in their water and go to the bathroom in their water, the quality of the water is a very important. A very large filter is needed. We suggest a minimum size filter that's made to filter 2 times the volume of your aquarium. So if you have a 40 gallon aquarium, you'll want a filter made for at least 80-100 gallons of water.

I had one in a 20 gal tank for our turtle. It was very bright. I’d start with one, you can always add a second if you feel necessary.

Yes, but they also need heat. We would suggest a 25w blue mini halogen in a dual low profile fixture with the UVB. The UVB will be very beneficial!

Hi there! Yes, two of them should be plenty. For the best heating and lighting, we'd suggest a 20” Pro Sol with a 50W White, 25W Red, and 2 Desert UVBs. Additionally, a 25W white in a Mini Dome for a concentrated basking spot would be appreciated by the bearded dragon too.That setup will also work for them in their future larger enclosure and only need to up to a 50W in the mini dome and 50W red for night. This setup will give them full coverage UVB, a good heat gradient, and a perfect concentrated basking spot. We hope you find this information useful!
