    I had a maintenance call this weekend. Need bulb replacements for some Vista pathlights. (model 4204 if you are acquainted) They had 10 watt T3 in them. I don't have experience with T3s and I haven't talked to the homeowner but I can't imagine that those were bright enough. Any suggestions for replacements? higher wattage halogen or xenon? LED?

    Halco makes a great bi-pin LED drop in and I believe James has a line of drop ins as well. That is what I would do in most situations like yours.

    Tommy's right. If the system was designed with 10 watt lamps, unless there is just a couple to replace the LED Retrofits would be a good suggestion. They aren't too much either. This way you won't have to worry about how they wired it. The LEDs aren't going to be as bright as a 20 watt T-3 however which will give you about 300 initial lumens or so. The LED's will give you 180-200 Lumens if I recall. I am sure James will chime in and correct me if necessary.

    10 & 15watt lamps are cheap to keep around. We stock about 100 at a time. If they want LED I would recommend the Illumicare gu5.3 bulb. In my eyes its equivalent to a 15watt halogen or a 24.4watt incandescent. Remember your color temp will be slightly higher. Just keep extras around. Illumicare has told me they have a failure of 1percent out of box. In my experience (over 300 last year) I see closer to 5-6 percent failure out of box.

    Tommy is correct. Illumicare ( www.illumicaregroup.com) makes a full line of "drop in" LED lamps including a variety of G4 BiPin LED lamps. Unlike the Halco products, Illumicare LED Lamps have been designed and manufactured specifically for use in enclosed fixtures and in moist environments. Developed by an outdoor lighting guy for outdoor lighting guys! :)

    No Need to correct you Tim. :)

    I would advise you to try the Illumicare G4 BiPin over the G5.3 when installing in those Vista path lights. The socket that Vista uses will not readily accept the G5.3 BiPin lamps. You can select from either the 19mm G4 or the 24mm G4 depending on the fixture style. Same light output from either, but the 19mm fits into more fixtures with its smaller diameter.

    On a side note, Brilliance LED has a new wedge-adaptor that fits the pins of our G-4 unit. Comes with each G4 bi-pin at no extra charge.


    A nice upgrade for the GE912 and GE921 wedgelamp fixtures.

    Also a new version of the AR-11 lamp coming very soon, including 3 beam patterns. And 20% brighter. If you stopped by our booth at LightFair, we had a sample on display.
