We use Ruud in all our lighting for large warehouse installs and for parking lots. We switched to Mh Pulse Start about 5 years ago when they became available and the warranty on them is 5 years on the bulbs and the light output is more than hps for the same given wattage, But now with these T5 making inroads we have used them in a couple of installs and they are great. Ruud has always backed there products and damage for us and the fact we can deal with them directly we don't have the cost and wait of going through a distributor. Give them a try and you'll never go back.
