This isn’t an easy question to answer, please read the following scenario:
Project: You are the counter person at a lighting showroom. Your customer would like to use a rail system in their kitchen. They need 6 spotlights and three pendants over an island. It will be a 15-foot run. Where do you begin to plan out this system?
The thought process is essentially this: How many watts will all the fixtures total?
How long of a run?
Given the run length and wattage load, which power supply makes more sense - the 12 or the 24-volt?
Given the maximum 300 watts for 12 volts and 600 watts for 24 volts, which power supply makes more sense?
For example, if all the fixtures in the above scenario are 50 watts, you’ll be working with a total of 450 watts. A 12-volt system could be considered because the run is 15 feet. However, due to its maximum wattage of not more than 300 watts per run, this rail would have to be divided into two separate runs with two power feed sources.
In this scenario a 24-volt system would be more economical. The maximum wattage is now 600 watts and only one power feed and transformer are necessary. This will also give you a cleaner look. The homeowner has to be made aware that it’s a 24-volt system and that replacement lamps are not as common as 12-volt lamps.
Lets assume you are going to do a 24-volt installation with a 600w remote magnetic transformer, this might be the project parts list:
- Six Quick Connect™ fixtures QF-194-CH
- Six shades G116-CH
- Six MR16 lamps 24V, 50 W MR16-EXN-24V-G
- Three Quick Connect™ pendant shades QP524-TQ/CH
- Nine Quick Connect™ adapters LM-QADP-CH
- Two 8ft Solorail™s LM-T8-CH
- One “I” connector LM-I-CH
- One power feed canopy LM-CPC-CH
- Approximately five ceiling standoffs LM-X3-CH
- One remote 24V, 600W transformer SRT-600M-24V
