Important Note :
LED bulbs are compatible with all types of magnetic transformers but if they exceed the maximum voltage rating for the LED bulb, the LEDs will fail prematurely. Many electronic transformers require a minimum load which is greater than that provided by LED bulbs. LED bulbs will usually not work properly (no light output, flickering, strobing) in fixtures that have integral electronic transformers in each fixture. We recommend changing the power supply to a 12 VDC regulated type if possible. Otherwise you must make sure that the voltage of your existing power supply does not exceed 14 Volts with the LED bulbs installed. Many standard Track Light power supplies will produce voltages as high as 16 with little or no load (LED bulbs provide little load). If you run a couple of standard bulbs with the LED bulbs this will usually load the power supply down to a safe voltage but it is always best to actually measure the voltage to make sure.

Important Note :
Only use dimmers intended for use with low voltage transformers. Common 120 Volt wall switch type dimmers will not work with low voltage systems. Dimmer manufacturers normally offer dimmers designed to work with electronic or magnetic transformers.

Important Note :
Excessive heat will cause LEDs to fail prematurely. They must be operated in an ambient temperature, not exceeding room temperature, for maximum life time. As the temperature rises above 23 degrees C, the life time goes down. Active cooling, such as a small fan, may be required if they are installed in a small enclosed space without ventilation. We do not make claims that these bulbs are drop-in replacements for all light fixtures with similar bulbs. We always recommend powering them only with a 12 Volt DC regulated power supply. Unregulated AC power supplies will often exceed the maximum voltage of these bulbs and cause premature failure which is not covered by our warranty.
