Light Emitting Diode (LED) Spots
Guidelines for Frontrunner

Product group covered: / Energy efficient LED spots or “reflectors” (as opposed to LED Classic Lamps), which can directly replace incandescent lamps and halogen lamps. Product lists are structured by lamp base (E27[1], E14, GU10[2], GU5.3 and G53). They have integrated control gear operated on main voltage (230 volts).
Product availability: / All products listed on meet the criteria listed below.
Potential energy savings:[3] / As the table below demonstrates, the luminous efficacy,expressed in Lumens per Watt (lm/W)of Topten LED spots is significantly higher:
Type / Best Topten example (lm/W) / Inefficient model (lm/W) / No. times more efficient
E27 / E14 medium / 58 / 6 / 8.7
E27 / E14 (very) bright / 73 / 7 / 9.4
GU10 medium / 79 / 6 / 12.2
GU10 bright / 85 / 7 / 11.1
GU5.3 medium / 88 / 12 / 6.3
GU5.3 bright / 62 / 14 / 3.4
Potential cost savings:1 / Cost savings on electricity throughout the lifetime of a Topten LED classic lamp can also be significant, especially when purchased on a large scale:
Electricity cost per unit (€) over 15 years
Type / Most comparable Topten example / Inefficient model / Price difference per 100 units
E27 / E14 medium / 9 / 79 / €7000
E27 / E14 (very) bright / 9 / 113 / €10,400
GU10 medium / 9 / 79 / €7000
GU10 bright / 9 / 113 / €10,400
GU5.3 medium / 15 / 79 / €6400
GU5.3 bright / 27 / 113 / €8600
The lamp life (h) of the best Topten models ranges between 25,000 and 40,000 depending on the type of lamp. Comparable inefficient models last for between only 2000 - 3000 hours and would therefore need to be replaced between 10 and 20 timesduring the lifetime of one Topten LED spot, depending on the type.

Procurement criteria – Updated: September 2014

The following criteria can be inserted directly into tendering documents. The Topten specifications are updated continuously. The newest versions are always available at .

Subject matter: / Purchase of LED Spots (‘Energy saving lamps’)
Technical specifications:
  1. Luminous efficacy: minimum 45 lm/W
  2. Average lamp life: minimum 15 000 hours
  3. Minimum number of switching cycles: 50 000
  4. Complete declaration, including: wattage, luminous flux, energy efficiency in accordance with , average lamp life, switching cycles, colour temperature, length and diameter and compliance with the RoHS Directive (2002/95/EC) and REACH Regulation (1907/2006).
Verification: Bidders must supply a declaration regarding their product’s compliance with the above requirements, supported by technical data and results from tests carried out in accordance with EN 13032 or equivalent, or a relevant third-party certification/Type I eco-label attesting to compliance. Where compliance with these criteria is dependent upon defined usage patterns or other factors these must be clearly identified in the declaration. Manufacturers must provide product information compliant with EU regulations No 874/2012, No 1194/2012 and No 244/2009.

Notes on implementation

  • The above technical specifications relate to LEDs only, there are separate guidelines forcompact fluorescent lamps (CFLs).
  • To maximise savings and minimise environmental impact, contracting authorities should assess whole-life cost when purchasing lighting. This should take account of the usage pattern expected, average lamp life and disposal costs.
  • Many design types which are suitable for replacing incandescent lights and which meet the above criteria are currently available, see for details.
  • Different types of energy efficient lighting may be suitable for outdoor use, areas with a high number of switching cycles or fixed luminaires. Public authorities who wish to develop tailored criteria for these situations are invited to contact the Procura+ team.

An expression of interest form is also available on for public authorities who would like support to apply these criteria in an upcoming procurement process.

What is Procura+?

Procura+ is an initiative designed to help support public authorities in implementing Sustainable Procurement. The campaign is run by ICLEI – Local Governments for Sustainability, the Topten partner for public authorities.
