LED Bulbs not for Dynamic Displays
Most of the seasoned veterans already know that the current generation of retrofit LED Christmas light bulbs (not the pre-lamped sets) are not suitable for choreographed displays but I thought it merited a mention here.
This is due to engineering differences between the sets and bulbs – primarily related to the way the voltage is stepped down in each scenario – and the bulbs receive an impulse when they are rapidly turned on and off due to a capacitor used in their design. So, flash, flash, fizzle.
So, take advantage of the retrofit C7 and C9 bulbs in your gorgeous static displays but as of now don’t purchase them for dynamic computerized displays.
