At a reasonable price really great product. Resistant porcelain bulb holder with good support for the lamps. Fair price and faster delivery. Have the parts almost all built and good quality has convinced me. Are stable and for the price I'm already where I verbaue another lamp track, fun ;-) If the cable ends and the required cable sleeves are plan - what more could you want! Who needs sockets can confidently strike here and obstruct successfully good commodity
