I have a ceiling with three recessed spotlights, and I just put these bulbs (11W 630 lumens) in because the others it had (2 halogen candle-type and 1 like this, 18W, don't know lumens) were 2700K, and I wanted daylight (6300K), because it's a room where the natural light is almost nonexistent.
However, now I'm feeling a little dazzled and I don't know whether the reason is because these bulbs might not be used without a ceiling covering them fully. More than half of the bulb is protruding from the spotlight.
The store employee told me that the spiral one may cause headaches, if it's not properly covered by the ceiling. He didn't say anything about the tubular one though, that's why I bought them. But now I'm feeling dazzled, and I don't know whether the reason is the above stated or other.
Is using this kind of bulbs without the ceiling covering them bad?
