I'm putting my venting issue on hold while I determine my lights. I'm being tempted by the LED option. No heat means I could just scrub and exhaust to the adjoining room without need for vent. I many still make use of the 2 inch PVC to pull in fresh air but not sure.

If I can do LED right at a reasonable price then I'll likely go that route. If not, I'll be back here working out my venting issue.
