    More questioons from a newbie. I have many 20W and 35W MR 16 lights. Can you give me general guidance as to where to use which bulb, and again, in general, which beam patterns work best on which applications. Thanks.

    Kind of an open ended question. I like to stick with 36degrees on both the 20 and 35 w/ MR 16's. I am sure others will ahve there opinons but how we do it at Unique is we provide you with either a BAB or FMW but then we provide you with designer lenses for spreading, softening, or narrowing the beam. This allows you to not go crazy come maintenance time. Trying to remember which beam spread was where can be a nightmare unless you do a really good job of documenting your initial installation. Most dont so the idea of using lenses seems to work well.

    Now which lamp goes where is really hard to generally say. I mean you can say that larger plants and architecture will merrit the 35 and smaller stuff will utilize the 20w. But Some will argue that 35 is too much for a L/S period. I tend to disagree, I love using 35w lamps in my designs. So I think for a better answer to your question here you should offer up so some examples as to what you are lighting up. Give us an example as to what kind of plants you have, architecture, color, and so on and so forth. Dimensions help as well. Then we can better assit you in selecting the right lamp and then the rigth light.

    Feel free to call me for more information. I could have my rep come out and give you some onsite assitance to better help educate you here.

    the 35 watter has it's place on taller items for me. If I am uplighting a 2-3 story home, 20 watts typically gets lost before it reaches the top. also on very tall trees like certain pines and oaks, I like the 35 watt.

    I would tell you to get some fixtures and lamps and play around with them to see the different effects for yourself. The question you are asking is very subjective, and you will get 10 different answers from 10 different people. You will ultimatly have your own opinion of what looks best, so therefore it will be up to you to "see for yourself". Until you have this knowledge, you could simply over-build your lighting systems to accept 35-50 lamps. If something is too bright, just change out the bulb. Just remember to re-check the voltage and adjust accordingly.

    a look at a good photometric chart will help you determine what will work and where but keep in mind. These can be found in many manufactures websites and catalogs

    Ambeint light.... is there a ton of street lights flooding your area where your going to need a 35 in place of a 20 just to see the thing ?

    Type of object being lit... I have lit 1 story brick homes which needed a 35w to reach the gables well... Same style house in white took a 20w to achive the effect. Similar deep dense gree trees will seemingly eat light on you and may even require multimple 35 w or more depending on thier size and the ambient light.

    Keep in mind when lighting trees especially fast growers... try to leave enough avalible wattage to upgrade to a higher wattage lamp at a later time.

    Nothing will teach you faster than getting some lights and playing at yours or a friends home.

    Also keep in mind often times multiple low wattage lamps will produce better results than a single higher wattage lamp Providing the light emitted will reach the desired destination. Joeys point on lenses is great but do not limit yourself to just 36 degree bulbs. I recall one project I was FLOORED at the spread of a 75w 12 degree shooting up 4 stories.

    thanks guys for all your help. I would be lighting tall italian cypresses, 8-10 ft lugustrums, many sabal palms, single story stucco walls, and juniper taupieries. What about holly trees - do those look good lit?

    its hit or miss on holly trees... it really depends on the individual tree and if there is something better to light around it.

    With ligustrums my experience is usually 2-3 fixtures if they are nice and full... if they are old mature large ones they can use 6 or more lights. Sometimes hard to get a client to shell out 12-1500 to light one tree tho.

    Your single story stucco walls will probably take 20w for the most part if they are light in color..... Palms depends on the size but do not think you can just plop one light in front of every tree and get the results you see on this site.

    Call AJ at florida outdoor lighting and tell him I sent you... he will get you set up with good prices on a real quality product line and he stocks more than you could hope for in your area. He also has seminars all the time.

    You really got some stiff competition in your area with oscar welch and bob kelly right there along with bela luce designs

    Not to mention Steve Riggs of Illuinations USA, but who the hell is Bob Kelly? Is he that retired guy that charges outrageous prices and gets one every now and then? Man, I wish I had a steady income from some other source and could consider this business "extra income". Billy, you really need to stop listening to Chuck and AJ so much. They are filling your head with too much crap!

    The retired guy is Oscar I beilive. I have never met Bob Kelly who is Elagant custom images. Oscar is an outstanding business man and has provided me with a great deal of useful information about marketing. Over lunch with him last year I got more useful info in an hour that I had in 2 seminars.

    I didnt get the feeling he considers his business extra income. I think he really enjoys taking his work seriously
