The UV spectrun has an enormous difference in the spectrum feild.

UVB is what your ig needs to metabolize the pre-vitamin D3 it gets from it's diet in to usable vitamin D3. This si what allows your ig to absorb calcium. Without UVB you ig WILL get Metabolic Bone Disease. Please do google search. Type in "Metabolic Bone Disease iguana" and read everything so you understand it better. This is NOT an option to go without until the weather gets better. As Merlin said, Your ig will be sick by then.

Errr, your link brought me to the lamp used for holding the bulb. Which bulb do you use? The bulbs are clearly marked and you should be able to tell what light you are using. I keep my basking temp around 90, because my ig feels very comfortable there and if she gets overheated, she moves, unlike other igs will not. Here are some food items I use to feed mind:
Collard, Mustard, Dandelion, and Turnip Greens
Nappa, Savoy, and Chinese Cabbage
Escarole, Radicchio, Bok Choy
Squash, zucchini, bell peppers

Those are a few examples. I give heavy amounts of the greens because they have the best calcium to phosphorous levels (calcium good, phosphorous BAD) with a fruit as an occasional treat. Hope this helps!!!

Also with lighting, if you do not use the UVB, you can search the net and find pics of the Igs that have MDB, which may look very disgusting and even scary. These pics have scared new owners into purchasing the right lights for their pets. I am not saying this as trying to 'scare' you into buying the proper lights, but it will show you how important these lights truely are. You can give your ig all the calcium possible in the food you feed them, but nothing can help metabolize this calcium unless you have the lights.

The cabbages and the bok choy should be fed only once in a great while if at all, not on a daily basis. Collard, mustard, turnip and dandelion greens are your staples and should comprise about 70-80% of the diet. The escarole is also good The squashes (orange type) green peppers, green beans, etc should comprise about 10-15% with fruit being added for variety and moisture.

Well I've been feeding him colard greens and cilantro is that okay? Also he now has a zoo med 75 watt basking bulb and a reptisun 10 uvb bulb so I think he should be doing fine.

I saw some it's horrible! Well mine should be fine now that I have all my stuff together.

Cabbages and Bok Choy don't get too much rotation in my diet, I am a big greens user and I give them veggies 3 times a week. Good thing you got your stuff together, so your ig won't have any problems!
