I do not use lights/reflectors for my geckos because they are in my room which has 5 windows in it, and they allow the sunlight to pour into the room, so that their day/night cycles are actually managed by the natural light outside.
All of my leo's have been eating mealworms for the past few months, and only mealworms. I have been told, though, that younger leo's like crickets more because they move more than any of the mealworms do. If you want them to eat the mealworms, then gutload them with whatever you prefer (I use oatmeal, powedered milk, and baby ceral with whatever fruit I have on hand for moisture which is either an apple or a pear, and a the only vegtable that I use is carrots.) Then, after they have been in the container then get a pair of tweezers (if you use your fingers they may not distinguish the mealworm from the rest of your finger
) and pick the mealworm up by the head, so that it will not bite at your gecko while you hold it infront of them. Usually the mealworm will flail around and your gecko will readily gobble it up. If it does not move, just shake your hand from side to side so that the mealworm looks like it is moving, and it will intice them to eat. Also, make sure that the mealworms aren't to large for your geckos. If they are babies, I suggest to use the smaller mealworms. Although it will take more for them to get full, it limits the ammount of impaction (which I have heard caused from mealworms) and the "Eyes Larger than the Stomach" syndrom, lol. If they are juvi's, use the medium mealworms, or what I buy for my juvi is the "Great Mealworms" or something like that, from PetCo. And for my adults I buy the "Super Mealworms" which they love. Make sure to dust the mealworms with calcium for the babies/juvi's every to everyother feeding. And for the adults everyother feeding if you don't just add the calcium directly to the gutload, which I do, and still lightly dust them for the juvi to make sure that he gets enough calcium. Also, when they are adults you can leave a bottle-cap full of the calcium supplement in the enclosure with them, so that they can lick at it whenever they want. Just make sure that you NEVER use CALCI-SAND. BAD BAD product and can lead to impaction because the geckos lick at it because it has calcium distributed throughout the sand, and end up eating the sand and causes impaction which could lead to the death of your gecko.
Hope this helps, lol
