The 3000K & 4000K GCJs are probably the most reliable ones available. The 3000K GCM & GCL are decent. The 4000K version of the two seem to have problems such as lumen depreciation and color temperature shift. The E-cobras that were installed recently in my area are still complete junk. I have not seen the Comfortviews used yet.
I see, I’ll have to go down to Cohasset, MA to see the Comfortviews.
