I need to replace my MVB bulbs soon, but can not remember which brand to get.
If I recall one of the 2 is considered a lower uvb output.
should i get exo terra or powersun?
Thanks

I like exo terra.

I have never used the MVB bulbs but this website has alot of useful info about the various brands and how they distribute UVB through a cage. Its a great site to read through to learn alot more about various UVB producing bulbs, the risks of some of the compact coiled UVB bulbs and the need of UVB to be provided for reptiles. I think it will be helpful for you in choosing the best UVB source for your dragons, depending on your cage setup and reptile needs.

Great site thanks!

I have used MVB for my Dragons for 2 years, I have been using Exo-Terra. A few weeks ago I had found a thread somewhere on MVB brands, and I half remember someone saying one was bad. I can not find that thread and did not think it was exo-terra.
From the site PHyou gave me, they do not test exo-terra, however do discuss T-Rex and every time they refer to the brand they put(latest version) or (discontinued version) which makes me assume it is the discontinued bulbs that I had read about.
Exo-terra is simplest for me to get, so I think I will continue with them.

*I use 160W on my dragons in custom cages, the back half of the top is open and I have the bulb secured at 24" from the bask spot at 100-110 temps.
And a 100W for my Tortoise at the same height with a temp of 90-95

The problem bulbs in the past were mostly the compact coil type UVB bulbs. I am not sure the guys at that site ever tested any of the exa-terra bulbs though I expect if you contact them, maybe ship them a few bulbs, they will test them. The main site I believe is in the UK, not sure if exa-terra bulbs are available there.

Hi: I use MVBs in some of my enclosures, and based on the research I did before purchasing them MegaRays are considered to be the best available. I can certainly vouch for the quality of the bulbs--I credit the MegaRays, phoenix worms, and TLC measures with bringing back a rescued dragon that was nearly lost to MBD. My animals really thrive under those bulbs.

The downside of the MegaRays is that they can only be ordered from the manufacturer, and they've had some fulfillment issues at times. They're also marginally more expensive than the cheapest prices you'll find on TRex and other MVBs--but I personally think they're worth it.
