Unique Climate Challenges in Brazil
When it comes to outdoor lighting, Brazil has unique challenges, thanks to its highly humid and unpredictable climate. Brazil outdoor lighting infrastructure demands adapting to its hostile weather. Typical, medium quality outdoor lights don’t stand a chance of long term survival in tropical regions because of the specific weather conditions and the challenges they pose.
Brazil witnesses, on average, 100 plus days of heavy thunderstorms each year that translates directly into power surges both due to lightning and grid spikes. No wonder, it has surge damage rates of above 35% which is unlikely for regular outdoor conditions in other than tropical regions.
To add to these unreliable ground conditions, Brazil experiences persistently high temperatures of around 30°C. The extreme humidity with above 80% RH during rainy seasons can be detrimental for the internal sensitive components of outdoor urban lights. These weather conditions call for specially made lighting solutions that can adapt to such harsh conditions and deliver consistent performance over the years without rapid tear or performance fluctuations.
Under such circumstances, Lead-Top’s LT154 series steps in to provide a solution where other average sensores de fotocélula fail to survive.
Let’s have a look at how Lead-Top’s certified IP67 waterproof photocell sensors present an all-in-one solution for Brazil’s highly humid and difficult outdoor conditions.

Lead-Top’s Professional Solution
Keeping in view the humid climate, consistently high temperature, and unusually high electric surge percentage in Brazil’s unique outdoor settings, we have specialized photocells with sealed housing that are tested and certified to perform under such unreliable conditions.
Our highly recommended product for Brazil’s specific conditions is the specialized LT154 Series. It is a heavy-duty electronic photocontrol. It is among the most resilient models, built to deliver consistently under difficult outdoor settings. Here’s what you can expect from this tropical climate photocontrol sensor especially during rain spells and thunderstorms.
- Superior lightning resistant photo sensor for rainy season
✓ These photocells feature 640J standard surge protection that can even be upgraded to 1280J for extra protection. It is made to resist the damage caused by electric surges during stormy weather. It deals efficiently with the power surges caused by both lightning and grid fluctuations during heavy downpours and lightning
✓It comes equipped with Zero-crossing detection technology that reduces arcing damage extending the life span of the photocells by minimizing the wear to its components
- Exceptional environmental resilience to ensure reliability and longevity:
✓ Our LT154 photocells are built to withstand extreme temperatures ranging from -40°C to +70°C for ensuring consistent performance under both the hot and cold spells typical to Brazilian climate
✓ IP67-rated waterproof housing of these photo controls protect sensitive and damage prone components against humidity, pollutants, and impact using the sealing gaskets that are waterproof
✓ High-density sealed construction is provided to keep sensitive components shielded and also resist the damage caused by impact.
- Proven reliability:
✓ 10-year warranty is a testament of our confidence in the quality of our photocells and our commitment to providing highly reliable products.
✓ 10,000 switching cycles are tested to make sure the photocell sensors have a long lifespan and can perform with consistency over the years. This reduces maintenance expenses.

Competitive Advantages
Our LT154 series have a huge edge over other photocells by our competitors, thanks to the unmatched features of this specially built series for the unique needs of tropical areas.
