im trying to decide if a Mega Ray is bulb i should get. around 3 weeks ago i just bought a 5.0 reptisun tube for my iguana, now that i have the money i am thinking of getting a mega ray. i am going to give my reptisun to my skink since she needs a new one, or i could just buy another reptisun and save money. my cage is 4x4x2. i am thinking of the 100w but i will then have to buy a clamp lamp. so if i get the mega ray all my reptile budget will be almost depleted. so should i get a mega ray and give the skink a new reptisun, or save up for some vet trips?
