GE range hood - JV348LSS works fine up to expectations. Although not a complicated product. I do request more detailed electrical/electronic info (I am a retired electronics engineer) as to the variety and/or restrictions on what types of compact fluorescent light-bulbs (CFLs) that can be used with respect to the 2-speed switch. Schematically, it looks like you place a forward-diode in series when selecting the night-dimm mode. What does this mean to various/all CFLs ?? Otherwise, GE - JV348LSS range hood looks and performs fine so far. I look forward to another 20+ year life .?.
