EZ Marquees are known for their Uniform brightness. Brightness of the EZ Marquees remains the same over a period of time whereas our competitors Marquee's brightness decreases and some of the LEDs will worn out.
The luminous intensity of an LED depends upon the current
going through it. It is also a known fact that the luminous
intensity degrades over a period of time. If the current flowing
through each one of the 3840 LEDs in the competitor’s
marquee shown to the right varies even as much as 10% and
the luminous intensity differs even as much as 20%, the result
would be a sign that will look great when first installed but
would need replacement within a few years because some of
the LEDs would be dimmer than others or simply burnt out.
In order to avoid this dilemma and have the marquee look as
good as when first installed, (remember Uticor’s reputation
in marquees is simply legendary) EZAutomation marquees
accomplish this by:
1. Using Matched Luminous Intensity LEDs
2. Carefully controlling the current through each LED
3. Reduce switching current losses to almost nothing
4. Use very efficient, 95% plus, switching power supplies
5. Perform a 24-hour burn-in test under power to weed out
marginal LEDs
