I bought in addition to the 20W and the 10W-Lux-Pro floodlights. Both can be well mounted, but the light is a bit strange (but felt a bit cold - despite "warm white"). The 10W lamps replace 58W fluorescent tubes in the barn and meet the normal illumination. However 10W enough, if you want to perform delicate work on the ground. The 20W version (with / without motion) examines the foreign area around the house - from 6m height. Here would be 10W enough to ensure sufficient brightness (door sign read, etc.) to obtain.
I can not say anything yet, because the spotlight only a few weeks are on duty, but I wonder if I (20W) and in the workshop is to assemble instead of 58W fluorescent lamps on longevity. - Presumably, if these give up the ghost - not "just happen" to save power, the nthe cost are still a bit high. The 10W version is enough to simply illuminate only courses / areas to detect obstacles.
