I have a red eared slider that is about 1.625 inches long. I have a heat/ UVA lamp. I was told at the pet store that this was enough for a RES. However, after doing research on he internet, I have found pout that it is necessary to have both UVA and UVB. I don’t have access to a UVB bulb. It is currently about 3 months until it becomes warm enough for the turtle to go outside to get natural sunlight. Can my turtle survive at least that long? Will natural sunlight supply enough UVB? If I do have to end up getting a UVB light, are there any bulbs that are UVB and UVA? If there aren’t, then how can I fit two bulbs on top of one basking area that is 6 inches by 3 inches?

Will it survive? Probably. But it may encounter health problems later. UVB bulbs will emit UVA also, but you will still need a source of heat for basking. Usually two bulbs are used, because of this. Mercury vapor bulbs will do both, but are a bit high-powered for small tanks.
