why on the to avoid list? i have had them for awhile and th e chams seem fine, but I know that the spectrum thing is particular and I want to replace the long bulb.
if you are not sure , then why would you take the chance? if you are going to have to spend $20 to replace the bulb , then why not spend another $20 so that you can KNOW it is safe? and if you replace the bulb with one that is questionable, you will be faced with the same dilema again in less than a year. if you have a chance to fix the problem now for an extra $20, and you dont, then what will you say to yourself, if one morning you wake up and find that he is not fine? a trip to the vet could cost you 5 x that. i would think that your chams health and your own piece of mind might be worth an extra $20, but thats just me. thanks to Dave Weldon for his constant vigilance on the subject
