Technical Specifications
Smart Lighting Technology for Malaysian Commercial Facilities
Smart lighting combines high-efficiency LED technology with intelligent control systems to deliver energy savings far beyond a simple lamp swap. A conventional T8 fluorescent fixture draws 72W and runs at full power regardless of whether a space is occupied. A Trexon Smart LED equivalent draws 30W at full brightness — and automatically dims to 9W (30% power) when the space is unoccupied, then brightens instantly upon motion detection. For a Malaysian warehouse operating 24 hours, this motion-based dimming strategy reduces lighting energy consumption by 60-80%, with the exact saving depending on actual occupancy patterns throughout the day.
Four core technologies drive smart lighting performance. LED retrofit replaces fluorescent and metal halide sources with chips delivering 190 lumens per watt — nearly triple the efficacy of T8 fluorescent at 100 lm/W. Motion sensors using passive infrared (PIR) or microwave detection trigger full brightness within milliseconds of occupancy, eliminating the "lights on in empty rooms" waste that accounts for 30-50% of lighting energy in carparks, warehouses, and office corridors. Daylight harvesting uses photosensors to automatically reduce artificial light output when sufficient natural daylight is available — cutting daytime lighting loads in perimeter offices and atrium spaces by 40-60%. Lux-level optimisation calibrates each fixture to the minimum light level required by MS 1525 standards for the specific task: 300 lux for general office work, 150 lux for warehouse aisles, 50 lux for carpark driving lanes. All fixtures are MyHIJAU certified, qualifying the upgrade for GITA 60% capital allowance and making the project eligible for green bank financing from CIMB, Maybank, and Public Bank at rates from 3.88% p.a.
Smart Lighting FAQ
How much can smart LED lighting save on TNB bills in Malaysia?
Smart LED systems with motion-activated dimming typically save 60-80% compared to T8 fluorescent baselines in Malaysian commercial facilities. A 50,000 sqft warehouse with 500 T8 fixtures running 24 hours pays approximately RM 71,500 annually in lighting electricity (at TNB C2 tariff RM 0.546/kWh). Replacing with Smart LED systems reduces this to RM 14,300-RM 28,600 annually — a saving of RM 43,000-57,000 per year. Payback period on the RM 140,000 upgrade (500 fixtures at RM 280 each) is typically 2.5 years before GITA tax savings and further reduced to under 2 years with the 14.4% GITA effective discount.
What is daylight harvesting and is it worth implementing in Malaysia?
Daylight harvesting uses photosensors to measure ambient light levels and automatically reduce artificial lighting output when natural light is sufficient. In Malaysia, with 12 hours of strong daylight year-round, perimeter offices and top-floor factory spaces can reduce daytime lighting energy by 40-60% through harvesting alone. Combined with motion sensing, total lighting energy reduction reaches 70-80% in well-daylit spaces. The technology adds approximately RM 50 per fixture to implementation cost but delivers the highest ROI in facilities with large window areas or skylights — common in industrial parks in Shah Alam, Petaling Jaya, and Johor Bahru.
Does smart lighting qualify for GITA tax incentives in Malaysia?
Yes. LED lighting retrofits and smart lighting control systems using MyHIJAU-certified equipment qualify for the Green Investment Tax Allowance (GITA) under the Promotion of Investments Act 1986. Companies receive a 60% capital allowance on qualifying capital expenditure, claimable against 70% of statutory income. For a company paying 24% corporate tax on a RM 200,000 lighting upgrade, GITA saves RM 28,800 in tax — an effective 14.4% discount on the project cost. Claims are submitted via Form JKST 1 to MIDA. Trexon provides full GITA documentation including MyHIJAU certification numbers, equipment specifications, and energy audit reports.
What lux levels are required for Malaysian workplaces under MS 1525?
MS 1525:2019 (Code of Practice on Energy Efficiency and Use of Renewable Energy for Non-Residential Buildings) sets minimum illuminance levels: General office open plan requires 500 lux; private offices 300 lux; corridors and lobbies 100 lux; warehouse general storage 150 lux; warehouse picking and packing 300 lux; manufacturing fine assembly 750 lux; carpark driving aisles 50 lux; carpark parking bays 75 lux. Smart lighting systems are programmed to maintain these minimums while dimming to the lowest compliant level, maximising energy savings without compromising visual comfort or DOSH safety compliance.
How long does a smart lighting installation take and is there disruption?
A typical Malaysian commercial installation completes in 3-10 working days depending on fixture count and facility type. Work proceeds zone by zone so only one area is offline at a time — operations continue uninterrupted in all other areas. For 24-hour manufacturing facilities, installation is sequenced during lower-production shifts with hot-swap procedures ensuring no total lighting outage at any point. Electrical connections require brief circuit isolations of 15-30 minutes per distribution board. Post-installation, IoT commissioning and lux calibration takes 1 additional day. Full system is operational with cloud dashboard access within 2 weeks of project start.

LED vs Fluorescent: Full Cost Comparison
Malaysian commercial buildings still running T8 fluorescent fixtures pay 2–3× more for lighting than they need to. Here is the honest, complete picture.
| Criteria | T8 Fluorescent | Standard LED | Smart LED (Recommended) |
|---|---|---|---|
| Wattage per fixture | 36–58 W | 18–22 W | 15–20 W |
| Lifespan | 8,000–12,000 hrs | 30,000–50,000 hrs | 50,000–75,000 hrs |
| Lumen output (2 ft) | 2,700 lm | 2,800 lm | 3,000 lm |
| Energy cost (10 hrs/day, 1 yr) | RM 780–1,260 | RM 390–480 | RM 200–280 |
| Dimming / occupancy control | None | Limited | Full IoT + DALI |
| Maintenance (ballast/tube) | Every 1–2 yrs | Every 5–8 yrs | Every 8–12 yrs |
| Heat output (IR) | High (UV risk) | Low | Very low |
| GITA / MyHIJAU eligible | No | Partial | Yes — 100% |
| Payback vs T8 | — | 2–3 years | 1.5–2.5 years |
Real ROI Example: 5,000 sqft Kuala Lumpur Office
A typical mid-sized KL office floor with 80 T8 fluorescent fixtures running 11 hours a day, 26 days a month.
Over 10 years, this single office floor saves RM 108,000 — enough to fully refurbish the space. Combine with commercial solar for 90%+ energy cost elimination.
Malaysian Commercial Lighting Standards (MS 1525:2019)
The Malaysian Standard MS 1525:2019 (Code of Practice on Energy Efficiency and Use of Renewable Energy for Non-Residential Buildings) sets minimum requirements for commercial lighting. Non-compliance risks failing your Green Building Index (GBI) assessment and GITA tax incentive eligibility.
Source: MS 1525:2019, ASHRAE 90.1 (reference standard). Smart LED systems from Trexon are commissioned and verified against MS 1525:2019 as part of every project handover.
