Lighting in a mining plant has a harder job than most people expect. Dust gets everywhere, washdown crews hit the fixtures with high-pressure water, temperatures shift through the day, and the lights themselves run long hours.
A unit that works perfectly in a regular warehouse can fail early in a mineral processing plant—and when it fails, you're looking at downtime and safety risks. Here's what to check on the environmental, electrical, and maintenance side before you settle on LED lighting for a mining plant site, with the IP67/IP69K tri-proof range as a practical reference.
Environmental Factors on Mining Plant Sites
Crusher halls, screening areas, conveyor galleries, workshops. These are dusty, damp spaces with regular washdown routines, and the lighting needs to handle all of it. Fixtures should be sealed against water ingress and able to hold up under high-pressure cleaning without losing performance.
The TUBU L9 tri-proof series carries IP67 & IP69K ratings and is specified to withstand 100bar (1450psi) @80°C high-pressure water washing. The PC housing is IK10 impact-rated; the PMMA version comes in at IK08, which lowers the chance of damage in areas with flying debris or equipment moving through.
- Dust and fines accumulate quickly. Use fully sealed fixtures with high IP ratings.
- Washdown exposure is part of the routine. IP69K supports hot, high-pressure cleaning.
- Chemicals and ammonia may be present in processing areas. Ammonia-resistant construction helps.
- Mechanical impact happens. PC IK10 and PMMA IK08 give you two levels of impact resistance.
Electrical and Performance Factors
Site power isn't always what you expect, so confirm input voltage, power factor, and operating frequency before finalizing the fixture list.
The TUBU tri-proof lights operate on 200-240VAC / 100-277VAC (50/60Hz) with PF ≥0.90 @220VAC, which covers a useful range of electrical setups.
CCT options include 2700K/3000K/4000K/5000K/5700K/6000K/6500K with CRI >80, so you can fine-tune illumination for inspection areas, task zones, or general coverage.
Model | Power | Current @220V | Luminous flux (150 Lm/W) | Luminous flux (170 Lm/W) | Dimensions Ø×L mm |
TBL92F-20W | 20W | 0.09A | 3000 Lm | 3400 Lm | 75×552 |
TBL94F-40W | 40W | 0.19A | 6000 Lm | 6800 Lm | 75×1152 |
TBL95F-50W | 50W | 0.23A | 7500 Lm | 8500 Lm | 75×1452 |
TBL95F-60W | 60W | 0.28A | 9000 Lm | 10200 Lm | 75×1452 |
With up to 170 Lm/W available, you can weigh lumen output against energy consumption when planning a larger installation. For site-level calculations, you'll want the full photometric and electrical data—request the technical specifications.
Specification Checklist for Buyers
- Confirm the area classification and cleaning method. Where high-pressure washing is part of the routine, choose IP67 & IP69K sealed fixtures.
- Match fixture length and lumen package to mounting height and spacing. The range covers 20W/40W/50W/60W models with flux from 3000 Lm to 10200 lm, depending on model and Lm/W variant.
- Select CCT based on the visual task. Options include 2700K/3000K/4000K/5000K/5700K/6000K/6500K with CRI >80.
- Review the mechanical installation. Surface mounting, suspension mounting, and linkable installation each suit different plant layouts.
- Plan for lifetime and maintenance access. L70 >54,000 hours at Ta 40°C reduces replacement frequency, which pays off in hard-to-reach spots.
Maintenance and Lifetime Considerations
Maintenance in a mining plant is expensive for a simple reason: work usually has to be scheduled around production. Every hour spent servicing lights is output lost, so fixtures that cut ladder time and replacement frequency carry real operational value.
The TUBU TBL92F/TBL94F/TBL95F series uses a BOKE driver with Lumileds/Hongli 2835 LED configurations and 304/316 stainless steel end caps. The working temperature spans -20°C~+40°C and the storage temperature is -20°C~+60°C, so check the ambient conditions at each mounting point before committing to a layout.
For washdown and dust-heavy mining plant areas, put the TBL92F-20W, TBL94F-40W, TBL95F-50W and TBL95F-60W side by side against your mounting height and coverage requirements. If you want help matching the right model to a specific building or bay, talk to our engineers—they'll walk through the layout with you.
Selecting the Right Mining Plant LED Solution
Mining plant sites vary too much for one fixture to cover every scenario. The TUBU tri-proof series isn't described as explosion-proof or intrinsically safe, so buyers should verify the area classification and applicable regulations before installation.
For general processing, washdown, warehouse, and workshop environments, the IP67/IP69K ammonia-resistant design is a practical LED option backed by CE, RoHS, CB, ENEC, RCM, SAA, DLG, and ETL certifications.
