I ABSOLUTELY love the guys at hellolights. They are a few bucks more expensive than AHSupply, but their service and shipping speed kick butt.
my first order came fast, but one bulb was shattered, despite the extreme amount of protective packaging they used (stupid FedEx handling). I called them, and they shipped a replacement bulb the same day and made FedEx picked the damaged bulb.
I ordered a coralife hood from them also, and it came quickly and undamaged.
