Yeah, possibly the T-version is the better choice. Unfortunately the non-T-version does not have a sensor, thus is powered up all the time to the full unless you switch it off manually and consumes energy that way. An even a sensor may be an issue, depending from the lamp as below a Brompton-bag on the carrier blog most lamps (respectively their sensors) assume it would be night, even in brightest sunshine.
