SASO 2902 Energy Efficiency: The Complete Specification Guide

Why energy efficiency is the real gatekeeper

Most specifiers focus on safety compliance when preparing for SASO 2902 — and safety matters. But the statistic we see in the field is clear: roughly 60% of SASO 2902 non-compliance issues for lighting products are energy efficiency related, not safety related.

The Saudi Energy Efficiency Center — SEEC (المركز السعودي لكفاءة الطاقة), working under SASO (الهيئة السعودية للمواصفات والقياس والجودة), has been progressively tightening efficacy thresholds since 2018. The Kingdom's Vision 2030 energy reduction targets mean these requirements will keep getting stricter, not looser.

What this means in practice: a fixture with solid safety certification but marginal efficacy will fail at customs just as definitively as one with a wiring problem. And unlike a safety issue that can sometimes be corrected in-field, an efficacy shortfall is a fundamental product design problem that usually requires re-engineering.

If you are specifying lighting for projects in Riyadh (الرياض), Jeddah (جدة), or Dammam (الدمام), you need to treat energy efficiency as a primary selection criterion, not a secondary checkbox.

Efficacy tiers and classification system

SASO 2902 uses a tiered energy efficiency classification system for lighting products. Products are assigned an efficiency grade based on their measured luminous efficacy (lumens per watt), and only products meeting or exceeding the minimum threshold are permitted entry into Saudi Arabia (المملكة العربية السعودية).

The classification system is built around the following tiers, from highest to lowest efficiency:

• Class A+++ / A++ / A+ — Highest efficiency tier. Reserved for the most efficient products on the market. These products qualify for Saudi Energy Efficiency Program incentives and are preferred for government projects.
• Class A — High efficiency. Meets all current regulatory requirements with margin. This is the target tier for most commercial and architectural lighting products.
• Class B — Medium-high efficiency. Acceptable for many product categories but approaching the regulatory floor. Check the specific product category's minimum requirement.
• Class C and below — Generally not acceptable for most lighting categories under current SASO 2902 requirements. Products in these tiers will be rejected at customs.

The exact thresholds are defined in the SASO 2902 technical regulation and its supporting standards. They are periodically updated — the 2024 revision raised the minimum for several key categories. If you have product data from before 2024, re-verify it against the current thresholds before assuming compliance.

How efficacy is tested and measured

Efficacy testing for SASO 2902 follows established IEC photometric methods, with specific Saudi requirements for test conditions and reporting. Understanding the test methodology matters because small differences in how you test can produce meaningfully different efficacy numbers.

Test standard reference

The primary test methods referenced in SASO 2902 for energy efficiency are:

• IEC 62722-2-1 — Luminaire performance, Part 2-1: LED luminaires (photometric and electrical measurements)
• IEC 62612 — Self-ballasted LED lamps for general lighting services (performance requirements)
• LM-79-19 — Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products (from IES)

SASO accepts test data from IECEE-accredited laboratories that demonstrate competence in photometric testing. The test must be performed in an integrating sphere or goniophotometer, depending on the product type and the claim being made.

Critical test conditions

These are the test conditions that matter most — and where suppliers sometimes fudge the numbers:

• Ambient temperature: 25°C. Efficacy must be measured at 25°C ambient. Testing at lower temperatures (e.g., 20°C) produces higher efficacy values that are not valid for SASO submission.
• Rated voltage and frequency: 230V / 60Hz. Testing must be performed at Saudi grid conditions. A driver that performs well at 220V/50Hz may show different efficiency at 230V/60Hz.
• Total input power. Efficacy is calculated as total luminous flux divided by total input power (including driver losses). You cannot use "LED chip efficacy" or "module efficacy" — it must be the complete product, wall-plug to light output.
• Warm-up stabilization. The product must be operated until thermal stabilization is achieved (typically 30–60 minutes for most fixtures). Cold-start readings are not accepted.
• Nominal wattage operation. The fixture must be tested at its rated power, not at a dimmed or boosted level that artificially improves the efficacy number.

Requirements by product type

SASO 2902 sets different minimum efficacy requirements for different categories of lighting products. These are the key categories and their current (2025) minimum thresholds:

LED lamps and bulbs

Self-ballasted LED lamps (A-shape, PAR, MR16, candle, etc.) have some of the highest minimum efficacy requirements, as they are directly comparable across manufacturers. Current minimum is 85 lm/W for general service lamps, with higher tiers going well above 100 lm/W. Low-wattage lamps (below 5W) have slightly relaxed thresholds.

Downlights and recessed luminaires

LED downlights (مصابيح سفلية) are the most common product type in commercial fit-outs and one of the most frequently failed categories. The minimum efficacy depends on the fixture's wattage and beam angle. Typical minimums range from 75–90 lm/W for standard downlights. Narrow-beam spotlights have lower thresholds due to optical losses. The biggest trap here: a downlight family where only the highest-wattage, widest-beam variant meets the minimum, but you are specifying a low-wattage narrow-beam version that does not.

Panel lights and ceiling fixtures

Panel lights have relatively consistent efficacy performance across the product category. Minimum threshold is typically around 80–90 lm/W for standard edge-lit panels and 90–100 lm/W for direct-lit panels. The failure mode we see most often here is panels with low-quality diffusers that reduce output by 10–15% compared to the test sample.

Linear lighting systems

LED linear lights — both suspended and recessed — are evaluated based on their total system efficacy including the diffuser. Minimums range from 85–100 lm/W depending on the product form factor. Pay attention to whether the certification covers the complete luminaire or just the LED strip inside — strip-only efficacy is not the system efficacy.

Floodlights and highbays

Outdoor and industrial fixtures (floodlights, highbays, streetlights) have lower minimum efficacy thresholds than indoor products due to the higher thermal and optical challenges. Typical minimums are 70–90 lm/W. However, the Saudi Energy Efficiency Program has been pushing industrial lighting efficiency harder than any other category, so expect these thresholds to rise faster than others.

Track lighting and spotlights

Track lights (إضاءة مسارية) and spotlights are evaluated based on their beam category. Narrow-beam products (less than 20°) have lower efficacy thresholds due to reflector and lens losses. Wide-beam track heads are held to higher standards. Common failure point: adjustable track heads tested at the most favorable tilt angle, but operating at a different angle in the field produces different thermal and optical results.

Power factor and standby power rules

Energy efficiency under SASO 2902 is not just about lumens per watt. The regulation also sets requirements for power factor and standby power consumption.

Power factor requirements

For most lighting products above a certain wattage threshold (typically 5W and above), SASO 2902 requires a minimum power factor of 0.9. This aligns with Saudi utility requirements to reduce reactive power on the grid.

What can go wrong:

• Low-cost drivers with passive power factor correction may show PF of 0.7–0.8, well below the 0.9 threshold.
• Some products meet PF at full power but drop below 0.9 when dimmed. Check whether the requirement applies at all dimming levels or only at full output.
• Products designed for residential markets sometimes ship with PF < 0.5 and no PF correction at all. These will fail immediately.

Standby power

Lighting products with standby functionality (smart lighting, sensors, emergency drivers) must meet standby power limits. The current maximum standby power consumption is 0.5W for most product categories. Products exceeding this limit fail the efficiency assessment even if their operating efficacy is fine.

Smart lighting systems with Wi-Fi or Bluetooth radios are the most common offenders here. Always verify the standby power specification for any connected lighting product.

Top reasons products fail efficiency testing

These are the most frequent causes of efficacy failure we see, based on actual project experience across Saudi Arabia.

1. Datasheet efficacy vs. measured efficacy gap

The number one reason. Supplier datasheet says 120 lm/W. Actual lab measurement comes in at 95 lm/W. The gap comes from using chip-level efficacy instead of system-level, not accounting for driver losses, and testing at idealized conditions. Never rely on the datasheet headline number for compliance purposes.

2. Driver efficiency drops at Saudi voltage/frequency

Drivers are typically most efficient at their design voltage. A driver optimized for 220V/50Hz may be 1–3% less efficient at 230V/60Hz. For a high-efficacy product operating near the threshold, that 1–3% can be the difference between passing and failing.

3. Thermal de-rating not accounted for

LEDs lose output as they get hotter. A fixture tested in ideal lab conditions (open air, 25°C) may run 10–15°C hotter when installed in a recessed ceiling, reducing both output and efficacy. SASO tests at 25°C ambient, but if the fixture's internal temperatures are higher due to poor thermal design, the efficacy drops accordingly.

4. Optical losses underestimated

Reflectors, lenses, and diffusers all absorb some light. The more optical elements between the LED and the output, the lower the system efficacy. Products with complex optical systems (tunable white, color mixing, narrow-beam collimation) often have lower real-world efficacy than simple direct-emitting designs.

5. CRI and CCT trade-offs

High-CRI LEDs (CRI 90+) are inherently less efficient than standard-CRI (CRI 80) LEDs of the same type. Warm white LEDs are less efficient than cool white. If your project requires 3000K CRI 90+, make sure the certification was done at that exact specification, not at 6500K CRI 80 which gives better numbers.

6. Component substitution in production

This is the insidious one. The product passes testing with high-quality LEDs and an efficient driver. Then the manufacturer switches to cheaper components in mass production to save cost. The product looks the same, but the efficacy has dropped below the threshold. This is why batch verification matters.

How to pre-verify before shipment

Do not wait for customs to find the problem. Pre-verify efficacy compliance before the product leaves the factory. Here is our process:

1. Demand the full test report

Not a certificate summary — the actual photometric test report. It should include:

• Test laboratory name and accreditation details
• Test date and environmental conditions
• Input voltage, frequency, and power factor measurements
• Total luminous flux (in lumens)
• Calculated efficacy (lm/W)
• Spectral power distribution and color metrics
• Photometric distribution curve (for directional products)

2. Verify the test conditions match reality

Check that the test was performed at 230V/60Hz, 25°C ambient, with the product thermally stabilized. If the test report shows 220V/50Hz, it is not valid for SASO submission. If it shows 20°C, the efficacy number is inflated.

3. Cross-check against product configuration

Confirm that the tested product matches what you are ordering in these critical aspects:

• LED type and binning
• Driver model and manufacturer
• Optics (reflector, lens, diffuser)
• Housing and thermal design
• CCT and CRI specification

If any of these are different from the tested configuration, the efficacy result does not apply.

4. Spot-check on sample units

If you have access to samples, run a basic efficacy check using a portable integrating sphere or a qualified lab. A quick 30-minute test can catch a 10–15% underperformance before you commit to a full container.

5. Confirm SEEC registration

Beyond the test report, the product must be registered in the Saudi Energy Efficiency Center's database. Ask for the SEEC registration number and verify it in the public database. A valid test report from a reputable lab is necessary but not sufficient — the product must be formally registered under the program.

Energy efficiency labeling requirements

Products that pass SASO 2902 energy efficiency requirements must carry the Saudi energy efficiency label. The label must be affixed to the product or its packaging and must include:

• The efficiency class (A+++, A++, A+, A, B, etc.)
• The rated power consumption in watts
• The luminous flux in lumens
• Product model and manufacturer information
• The SASO energy efficiency label logo
• Arabic language text alongside English

The label must be durable and legible under normal use conditions. We have seen shipments delayed because the label was printed on a sticker that fell off during transit, or because the Arabic text on the label was incorrect or missing.

For products sold in retail packaging, the label must appear on the front of the package in a specified size and position. For professional/contractor products shipped in bulk, the label may be on individual product cartons or on the shipping pallet, depending on the product category.

Final verification checklist

Before you approve a lighting product for shipment to Saudi Arabia, run through this energy efficiency checklist:

Energy efficiency compliance is not a box-ticking exercise — it is a fundamental product performance requirement that directly impacts whether your shipment clears Saudi customs. The cost of getting it wrong (detention fees, re-shipment, project delays) is orders of magnitude higher than the cost of verifying it correctly the first time.

At Yakeen, every fixture in our Saudi product line is photometrically tested and SEEC-registered at the exact configuration we sell. We publish the actual test report efficacy numbers, not marketing claims, and we provide the full SEEC registration documentation with every quotation.
