NOS Black DTL Electronic Photocells
These are not sensive at all for electronic photocells. They're very nice units though and probably built very well. Thansk again for these Darren! The left on is from April 2006 and the right one is September 2006.

It's all about the foot candle settings. I have blue ones of these that are not sensitive either but I have brown ones that are extremely sensitive.

I have a few used brown ones too. One's a dayburner while the other two work well. They're pretty sensitive. Narragansett Eelctric (NECo) ordered them in brown because they wanted the 120V units to stand out from the gray multivolt units. I don' see why though since every light used by NEco was either 120V or 240V with a 120V PC receptacle. They could have been using 120V units all along and since they come standard in gray it makes plenty of sense to do so. They didn't switch to 120V controls until a couple years after they started using 120V ballasts. After 1989 (or a year or so earlier), all their new lights were 120V reguardless of lamp type. Before they were 240V with 120V PCs, even the HPS ones.
