What is the best turtle UVB bulb wattage?

Turtles need the right kind of UVB bulb to help them grow healthy and to maintain the right amount of nutrients throughout their day. Without some source of UVB light, turtles will eventually develop metabolic bone disease.

What is the correct wattage of UVB lighting for turtles? UVB bulb available in different watts, such as 50 and 100-watt bulbs. In this post, I will help your figure out the best uvb bulb wattage for turtle.

#1 How many watts do I need?

wattage is a measure of electrical power. Basically, the more watts, the more power and the more electricity is being used. The choosing between 50, 70 and 100-watt is depends on your circumstances.

If you are using a small aquarium that about 50 gallons and you use it to keep 1 or 2 turtles, you may only need a relatively small basking area, where your two turtles can bask at the same time. Then you should option for a 50 to 75-watt UVB bulb.

However, in the contract, if you have a bigger aquarium about 90 gallons and more, and you are keeping more than 2 turtles in it, you will need a larger basking area, where are large enough for them to bask on. A 100-watt UVB bulb will be perfect for your tank.

Since a 100-watt turtle UVB would produce a bit more energy, it would also be able to produce more heat, as well as have a larger basking diameter. Due to this, you would be able to get a large basking area using a 100-watt UVB bulb than a 50-watt UVB bulb.

#2 How far away should I place the UVB bulb from a turtle?

Once you get the right wattage bulb for your tank, the next consideration factor is how close you will need to place your UVB light to your turtle. Since UVB bulb also produce heat, and you will want to maintain a basking area with a temperature of 85-90 degrees, you will certainly need to place a 50-watt light closer than a 100 watt light.

Generally, it is ideal to create the distance between 8-15 inches. However, to achieve the ideal temperature you should follow instruction manual on any light you purchase as well as manually take the temperature of your basking area once it’s all set-up.

It is prefer to place a 50-watt uvb bulb around 5-7 inches away from the basking area. While A 75 watt light will need to be placed around 7-9 inches away. 10 to 12 inches is the ideal distance to place 100-watt bulb from basking area.
