thanks! For heat i have the white lamp on (day only), a under tank heat pad(turns on when light turns off) and the red light stays on 24/7. You cant see them but ive got 3 seperate thermometers and hygrometers all in different areas to see temps/humidity. Everything falls right where it should at all times. Why would i switch the light out for the ceramic heat emitter? given that the temps are correct and the "daylight" is on for a regular cycle i see no point in wasting money on a che.
