Another grow light question...sorry!
 

I'm really missing being able to grow some orchids, particularly, high light ones. My setup is temporary, growing right now on a fairly large screen enclosed patio but the light isn't the greatest....northeast. It's better this time of year, able to grow Dends. and a few lower light catts but, most of my Catts are now hanging from the palm trees in front of the house....I'm not getting to enjoy those, though.

I've got one corner on the patio where, when it rains, will stay dry enough/safe enough to put up shelving with lights.

Can anyone advise me if this following link for some grow lights, would be a good setup for growing on a 3-4ft. wide unit? the right lighting I'd need?

They work WONDERFULLY! Low energy usage (compared to many other options and lower heat output - but you WILL notice a difference in your electric bill).
I have a 6 tube unit that WORKS GREAT!
