Comparison 101: 4 Things To Be Aware of When Buying LED Dome Lights


With time, all products evolve and are improved so as to deliver a better performance. This, in turn, presents buyers an entire variety to choose from. It also leads to this question..

Which one should I buy?” I can assure you, with 100% certainty, that we have all been there. Browsing through pages on the web, looking through several catalogs, going through technical terms; all of this, in an attempt to compare which product is suitable for your requirements.

The LED lights that are currently replacing traditional lights around the world, are also evolving to deliver either smarter or more efficient or user-friendly applications.

Wondering how to differentiate between LED dome lights?

This case study will help you make the catch; we’ll look at a comparison between our (NEW) dome lights and its alternate from another company and the top 4 things to be aware of when buying an LED dome light.

V-TAC Dome Light VS Alternate Dome light

1. Integrated Emergency Combined Driver

In each of the lights, an emergency kit is included, making it suitable for use in corridors, parking lots and/or garages of offices and residential areas in case of power failure. However if you notice closely,

The Auxiliary functioning driver comprising Driver and the Emergency kit, of the V-TAC dome light, together complies with the IEC standards & EMC .

In the latter product, however, the compatible emergency kit & driver acts in a parallel bypass circuiting, which reduces the lifespan of the whole system, during each recharging cycle.

2. Battery

Ni-Cd batteries have a higher number of rechargeable cycles, in comparison to the Li-ion battery and can operate over higher temperatures, unlike the Li-ion battery.

The Li-ion battery, however, does not require periodic discharge, while the Ni-Cd battery requires full discharge before recharging. However, the Li-ion battery has a shelf life based on the life of the battery and is not dependent on the charging/discharging cycles.

3. Quality of LED and heat dissipation

LED lights are a lot more efficient, considering that they are made from SMD technology. However, the quality and placement of the chips on the circuit board have a direct impact on the heat dissipation and hence, on the lifespan of the luminary.

The V-TAC dome light has LEDs aligned in a larger surface area on the circuit board for efficient heat dissipation, which in turn leads to lengthy lifespan. The latter, though, has LEDs aligned in a smaller cross sectional area, leading to lesser heat dissipation which in turn leads to lumen depreciation. As a result, the luminary would have a reduced lifespan.

4. Emergency mode functioning

The V-TAC dome light has all LED chips connected to the emergency panel – this means that all LED chips will function during an emergency, providing sufficient light. The alternate, in spite of having SMD technology chips, has ONLY one LED chip working under emergency conditions.

V-TAC offers four different types of this model:

 V-TAC's 2D Bulkheads

  1. LED 2D Bulkhead Dome Light
  2. LED 2D Bulkhead Domelight with Microwave Sensor
  3. LED 2D Bulkhead Domelight with Emergency Battery Back Up
  4. LED 2D Bulkhead Domelight with Built-in Microwave Sensor and Emergency Battery Back-Up
