Out of the two this is better for UVB BUT lets face it the heat from a fluorescent is no where what you need for a turtle so I would suggest this one with another regular incandescent bulb for the heat , just make sure it ( incandescent) does not get wet , cheap and breaks easy if got wet.

That other one yes "some" heat but as stated above not enough with fluorescent's for heating a turtles ! This other one is also a lot larger it's 200 watts and cost more . Watch the specifics on bulbs. On fluorescent the more coils the higher the wattage . Your are comparing a 3 coil to a 5 coil and one must watch how a company rates bulbs and or words used.
