Normally open(NO) and Normally closed (NC) are terms used to define the states that switches, sensors or relay contacts are under when they are not activated.
A NO contact or a normally open contact is the one that remains open until a certain condition is satisfied such as a button being pressed or some other manner of activation such as those based on temperature, pressure, etc.
A NC contact or normally closed contact is the exact opposite of NO contact by function. It remains closed until a certain condition is satisfied.
Lighting control cabinets typically control a group of street lights or advertising signage from a "control cabinet". These controls have historically provided on-off functionality based on the time of day using an "astronomical clock"-based switch or daylight photosensor. Lights are controlled in groups with no individual control over a specific light.
Although new controllers such as Tondo's Edge-IQ controller have replaced the cabinet-based approach with new technologies that include advanced dimming, remote cloud-control, and support for functionality including sensors and switches, there are many outdoor lights and signs that do not support on-lamp control. Tondo's Cabinet-IQ controller provides new advanced IoT technology support for existing cabinet-controlled lighting.
CAT-M/LTE-M and NB-IoT are similar but have differences that may make one suitable over another, or simply selected based on the support for one or the other that is available in your area.
NB-IoT uses a narrow bandwidth of 200 kHz, where CAT-M uses 1.4 MHz. The maximum data rate for NB-IoT is ~ 250 kb per second, with CAT-M1 reaching ~ 1 Mbps. CAT-M is marginally less energy efficient than NB-IoT. Although NB-IoT has a lower speed, both NB-IoT and CAT-M are suitable for sensor communications since sensors typically do not require much bandwidth.
Both NB-IoT and CAT-M1 are supported under the 5G technology specifications and therefore are ideal for selecting as a standard for sensor communications.
CAT-M wireless (aka LTE-M) is a low-power wide area network (LPWAN) cellular data transmission standard that operates over the data and physical layer. CAT-M was designed for IoT projects, with an average upload speed between 200 kbps and 400 kbps.

The Power of Dimming and Extended LED Fixture Lifespan
Tondo Smart Lighting control vs Dusk-to-Dawn impact on streetlight fixture maintenance
One of the most compelling benefits of Tondo Smart Lighting is the significant reduction in maintenance costs. These savings are not just incremental; they represent a fundamental shift in how municipalities manage their lighting assets.
Extended LED Lifespan: Tondo Smart Lighting significantly extends LED fixture lifecycles. Pre-dimming, the average LED lifespan is 14.6 years for a fixture rated at 60,000 hours. With Tondo’s Smart Lighting control, LED lamp lifespan extends to 39.0 years. By dimming the lights, the LED junction temperatures are reduced, decreasing thermal stress and slowing lamp degradation (sources: OSRAM, Tan, Kai Zhe & Lee, See-Keong & Low, Heng Chin. (2021)). Further, components such as capacitors are also affected by lower operating temperatures facilitated by dimming.
Reduced Failure Rates: The effect of longer fixture lifecycles reduces fixture maintenance costs with fewer maintenance events. With Tondo’s Smart Dimming, cities will experience considerably reduced fixture failure rates compared to dusk-to-dawn operations.
