    I am experiencing a problem with some Hadco Pathlights that we installed just over a year ago. The fixtures are a Hadco Model MUL4. They take a 20watt bi-pin lamp. I have had repeated calls from the homeowner that certain fixtures are not operating. What I have found is the lamps seem to be almost out of the sockets, or they are not making very good connection with the fixtures' sockets. If I simply tap on the top of the lamps, they come on and function properly. Is this a Hadco malfunction? Could the lamps be coming loose due to vibration, etc.? I am baffled by this one!

    vibration ? whats vibrating ? any signs of the kids hitting them with a ball or something ? Dogs beating them with thier tails ? Something to knock the bulb loose ?

    Sounds like the spring contacts in the socket are too deep in the sockets themselves and barley making contact.and sort of pushing them up. Have you tried a SMALL dab of hi temp dielectric grease ? I mean the smallest bit of it. Also are you using QUALITY bi pins with the right base pin size ? They should fit snug but not so you have to force them in

    Hadco had a major problem awhile back with Leviton sockets. The wires would pull out of the back of them. Your problem may be the lamps. What brand are they? I think bi-pin T-3's are some of the worst lamps available for outdoor lighting. They are too fragile even inrush current blows them to smitherines. You tap them and the filament fuses temporarily.
    You're better off with xelogen.

    I am using T-3's from my distributor. I am willing to use whatever lamp will fix the problem. There is no brand markings on the lamp box that I have. I will check with my distributor to check the brand. If the problem is with the springs in the sockets, is there an adjustment I can make to fix the problem or should I just replace the sockets?

    Hadco is aware of a t3 bulb problem. I agree with Mike about the t3 being a bad bulb and I have been talking with Lew Waltz and a few other about alternatives. They, for a while were shipping Satco bulbs and now have moved onto something else...which is also pathetic. As these bulb blow after 300-400 hours they are being replace a few too many times and the sockets loosens...also sometimes contractors grab a bi-pin but the wrong bi-pin and put it in there...this loosens the socket...I would suggest replacing the fixtures and/or sockets. Why havent you checked with your distributor, he should know this info? He should be getting you new fixtures and getting an RMA on those defective ones.

    Make sure that you are using a quality lamp. I use Ushio for all of my projects and I have very few lamp issues.

    Thank you for all of the replies! So do the majority of you feel this is a fixture issue or a lamp issue? My supplier keeps telling me they will get back to me, and so far I have had no success with them. I want to provide good service for my customer and I appreciate all of your input.

    I designed all of my fixtures around the MR-16 lamp including my copper spreadlight (see below- a bit crooked in the photo)for the simple reason that the T-3 is so bad. I have had enormous success with the Sylvania Tru aim Titan. In my estimation it's the best all around MR-16 dollar for dollar in the world. A close second to the GE constant color which is priced too high. I install around 10,000 lamps per yr. between new installs and maintenance with very little occurance of pre-mature lamp failure.

    My vote is on the lamps, you have been knocking the energized filament together to complete the circuit, which goes back to open during cooldown. You are getting off to a bad start with your clients as far as perceived quality if ever use the manufacturer supplied lamp. I second the Syl. Titans or GE Constant Color if you’re using halogen lamps.

    If I were you I'd get on the phone with the supplier and tell them to put me on hold while he calls Lew Waltz cell phone or at least someone at Hadco and gets a remedy...you are putting your business at danger by being patient!!!!
