However, it is important to remember that Micro-Brite bulbs use different technology to dim than incandescent; therefore, voltage setting adjustments may be necessary to maximize the dimming performance of the Micro-Brite bulbs. For correct installation, follow these simple steps: First, install all of your new [Litetronics Micro-Brite](https://blog.litetronics.com/product-category/cold-cathode/?fwp_categories=cold-cathode) light bulbs. Once installed, run the voltage all of the way up; then, slowly turn down the voltage until the lamps just begin to flicker. From this threshold, raise the voltage about 3 volts. This is your new low voltage setting.
