But it actually does produce red light from it... actually less than a viewer bulb does but idk maybe Im misunderstanding you but heres a link of the size and exact look alike.
That wouldn't work, it still produces white light just through a red filter. The red bulbs most people use produce infared light which the geckos can not see.
Ok yea I get what you saying Im pretty sure that was what Tommy13b meant... Well I went and picked up a natural moonlight bulb basically becauseit produces less heat than the red. It looks pretty cool to. Doesnt seem to bother him either.
