MR16 Standard Base LED Bulbs for Recessed Lighting

I got some bulbs that need replacing in some recessed ceiling lights. The bulbs that were in there were MR16 with a standard E26 base. I managed to find some replacements that were LED but they say they are not suitable for totally enclosed fixtures. Would it be okay to use them? If not does anyone know of any LED MR16 bulbs that are safe to use in enclosed fixtures?
