Indoor Lighting

Standards for Indoor Lighting

When purchasing indoor lighting, buyers have several options for energy certifications available to them including ENERGY STAR, FEMP-designated products, DLC, and DLC Premium. Buyers should specify one or multiple certification levels that all indoor lighting products supplied must comply with. Our team has assessed the four lighting standards and determined that in general for commercial applications, DLC Premium has the highest efficacy requirements for indoor lighting categories.

Products that do not meet or exceed DLC Premium standards will not be considered for the bid.

The Vendor shall submit manufacturer cut sheets for each model of indoor lighting product supplied indicating an energy efficiency rating that meets or exceed DLC Premium standards.*

*If your product meets or exceeds DLC Premium qualifications, but is not officially listed as a DLC Premium product, please also submit a third-party testing result indicating how your product meets the prescribed energy efficiency requirement.

[For recurring purchases/indefinite delivery/blanket purchase orders] Vendors shall submit a sample Green Products Report to [your organization] with the invoice. This report will serve as an example of the regular Green Products Report expected during the duration of the contract and should include the type of product supplied, quantity, dollar value, and type of green certification the product qualifies for, for all indoor lighting products supplied.

[Option 1] The Vendor will be evaluated based on the Vendor’s ability to verify that all indoor lighting products supplied meet or exceed DLC Premium qualifications.

[Option 2] The Vendor will be evaluated based on Best Value as assessed through life cycle cost analysis. Vendors are required to provide the cost for each product using the life cycle cost formula below:

LCC = I + Repl − Res + E + W + OMR + X
where:

LCC = Total LCC in present-value dollars of a given alternative
I = Present-value investment costs
Repl = Present-value capital replacement costs
Res = Present-value residual value (resale value, scrap value, salvage value) less disposal costs
E = Present-value energy costs
W = Present-value water costs
OMR = Present-value non-fuel operating, maintenance, and repair costs
X = Present-value other costs (benefits treated as negative costs)

Outdoor Lighting

Standards for Outdoor Lighting

When purchasing outdoor lighting, buyers have several options for energy certifications available to them including ENERGY STAR, FEMP-designated products, DLC, and DLC Premium. Buyers should specify one or multiple certification levels that all outdoor lighting products supplied must comply with. Our team has assessed the four lighting standards and determined that in general for commercial applications, DLC Premium has the highest efficacy requirements for outdoor lighting categories.

The table below gives an example of the variability in efficacy levels for the different types of certifications available for outdoor lighting.
