I trust Pets & Ponds, in fact I have been using them for over 4 years, and all their bulbs are new, and very well shipped. Once the ends were crushed in shipping and I could not use the bulb, and they sent me a new one without a shipping/return charge. I highly recommend them. I buy my 48" Reptisun 10's from them for 32.99, and have not found a better price so far. I cannot buy these lights here in my town, or anywhere else in BC. In fact, my last trip to Vancouver at King Ed's Pet supply was a loss, as they do not carry that size anymore.
All I can say is that the lights are well packaged, and my dragons have been doing very well. So the bulbs must be good.
