That describes a certain type of mercury vapor bulb, but they're so powerful that they're usually (AFAIK) used by/for free-range, where they're a considerable distance (several
feet) above basking.
They are not flat.
For chameleons, we need 3 kinds of lights:
- UVB (linear T5 running full width of the enclosure, either Reptisun 5.0 or Arcadia 12%)
- Basking, in order of preference:
- Old style household incandescent (NOT LED)
- Incandescent flood (NOT LED and NOT spot)
- Halogen flood (NOT spot)
- Plant lights (Currently, LEDS are more efficient, economical, and greener)
It may not be the most convenient, but it makes the most sense.
- You can adjust/aim each independently of the others to get the best "balance" for your enclosure.
- If one blows, you don't lose 2 or 3 functions while waiting for a replacement to be shipped.
