    I did a bid today for a current Christmas light customer who has an installed Focus lighting system. It is 3 years old, and he has never replaced a bulb, but recently 6 have went out.

    He is real happy with the system, and I have no experience with Focus, but the fixtures seem to be sturdy and well built, provide light without seeing the source, and further it is not in his budget to replace it, so I just agreed to rebulb all the fixtures, trim bushes around them, re set the angles etc, like we do for our yearly rebulbs.

    I have not used par 36 well lights in a while, and noticed they have xenon/halogen 5000 hour bulbs now, and was wandering if you guys have tried those.

    I know I'd rather do a mr-16 well light, but he already said no, just rebulb.

    any negatives? I am thinking 20 watt floods to replace the 20 watters he already has.

    They are better than the incandescent version. They cost a lot more when compared to mr16 lamps. When purchasing lamps, try to buy well known brands like GE, Ushio, Sylvania. There are a lot of no name brands made in China & Taiwan that will not give you proper lamp life. Prism Brand is one that I am testing out right now. If anyone uses this Brand please give feedback. :confused:

    A long time ago, I believe I used Prism 3156 wedge base lamps. I had some failures, and ultimately blamed the lamp and stopped using Prism altogeter. In hindsight, I don't believe it was necessarily the manufacturer in this case. As mentioned in an earlier post, wedge base 3156 lamps can be a pain in the butt, and we continue to have problems with them no matter what manufacturer we use. I would give Prism another try if I see that others have had some good results. I have had very good results with the Osram Sylvania products.

    I put in three kichler par 36 well lights with 35 watt PAR bulbs and like them a lot, but please watch out for the 20 watt bulbs! I was talked out of them by my distributor (not certain which manufacturer had them), there is a high failure rate.

    Paul and someone else posted here that had a problem with the 20's, also.

    I'd actually like to go 25 or 35 watters, but he is maxed out on transformer and a bit on wire capacity. there is one 10 guage wire coming out of the transformer, and at some point splits into two 12 guage wires. there are 9 fixtures on one and 6 fixtures on another, with about 80 feet from transformer.
    300 watt transformer with photo-cell and clock.

    at 15 fixtures 9 are wells with 20 watts each, and 6 are pathlighters with 1141's - 17 watts each. my math puts that at 282 watts, and i'd rather not upsize at this point.

    voltage is running from 10.6 to 11.8, not perfect but acceptable to me since I did not do the install. strange thing, the two lowest voltage pars went out and some of the higher voltage still work. huh, go figure.

    I'm hoping the dimness I'm seeing from the pars currently installed is from age, they are also 20 watts. also the xenon should be a little whiter color, but I won't know until I try.

    if no one can chime in with negatives by tomorrow, I'm gonna go ahead and order the bulbs, and a couple spares.

    thanks so far for chiming in.

    With lamps you have to remember this: everything you gain, there is something to sacrifice. With xenon lamps, they will last longer, but they will not give you the color rendition of halogen. The halogen lamps are going to burn whiter, not the xenon.

    I think that it is a known fact that no one can make a quality long lasting 20W Flood Par36 right now. Fixtures are eating the GE Hadco lamp and the
    PRISM HaloXen like candy. Fx has a new 20 watt lamp, but I don't think that it's acceptable due to funny light output close to the lamp and photometrics seem very tight compared to others.

    David, where are you going to get replacements from?

    I have a local distributor that can get FX "xelogen" or xenon with halogen, also,, stock these bulbs. It really comes down to either installing 2000 hour halogen's or 5000 hour xenon/halogens.

    I don't really have the option of not using pars, just the option of someone else doing the job. the current ones are not marked halogen, and are pretty yellow-dim, so even if xenon's are not as white as halogen's, It will be an improvement.

    I have noticed that the halogens are rated a few more lumens than the xenons. perhaps that takes into account the color.

    I'm gonna go ahead and give these bulbs a shot. I appreciate the comments, and will try to post before and after pics.

    I will put my 2 cents in regarding lamps. I was introduced to the industry by Unique - as a result my 1st couple of jobs all had Ushio lamps. I had no burn out problems at all. Then I started to experiment with other fixtures and I ended up using Prism lamps. Prism lamps SUCK! I have had a lot proplems with the Prism lamps. Right now I am experimenting with Atom's Xenon MR16 and / or Ushio only. Are any of you familiar with Atom Lighting?
