I have tested quite a few MVB's with my meter since getting it through the group. I have been disappointed in most of them---especially Nature Zone and FSS. The readings on NZ were 5 at times...FSS did not get above 40. Powersun's and other popular brands were problematic as well.
I have recently switched over to Trex completely after reading the info in the group. Unfortunately this was before Bob Mac came out with his line of products. I am not saying Trex is bad--it happend to be in the top 3 I would recommend, in between westron and megaray.
I now have the mega ray sb flood installed in my bearded dragon cage....the readings after 1 week, through the screen are 225 --- so far the best I have seen in this house. I plan on switching over completely during my next bulb change. What I really like about these new bulbs is:
1) There is a product for each animal in the house--as close to species specific as anyone has come so far.
2) I trust Robert MacCarger--he loves animals
3) Each product from the
UVb bulbs to the
CHE alternative mega heat---is ground breaking.
If anyone has not tried these bulbs I suggest starting with one and seeing for yourself.
We Love You Bob
