Welcome to the California Retail Lighting Shelf Survey (CRLSS) Online Tool

Tool created by DNV GL Sustainable Energy Use for public use.

No part of this website or the CRLSS Tool may be used for commercial purposes.

Funded by the California Public Utilities Commission (CPUC) Energy Division, DNV GL created this tool for public use. The tool enables interested parties to examine shelf stocking data for replacement lamps in retail stores located in California’s electric investor-owned utility (IOU) service territories (PG&E, SCE, and SDG&E) as well as the comparison states of Arizona and Georgia. The data covers several time periods between 2008 and 2016.

This tool enables users to assess the general availability, diversity, and pricing of replacement lamps available to consumers during different time periods, including IOU-discounted and non- IOU discounted lamps of several technology types (including compact fluorescent lamps [CFL], incandescent and light-emitting diode [LED] lamps, and others). The data may be examined by retail channel, lamp type, IOU service territory, and other groupings to reveal further details regarding the replacement lamps available to California consumers over time. Users can also access data on replacement lamps available to non-California consumers.

Recommended web browser: Microsoft Internet Explorer (IE) 11.0 and above are recommended for using this Tool.

Overview

Lighting retail store shelf surveys involve visits to retail stores to record comprehensive inventories of the lamps stocked in those stores. Field researchers gather information from store displays and lamp packaging including details on lamp style, wattage, lumens, price, and so on, to support evaluations of California’s residential and upstream lighting programs. Researchers collected data in several phases as shown in the table below. Later data collection phases include more comprehensive data on replacement lamps, while earlier phases focused on specific CFL and incandescent lamp types.

 * Data collected in PG&E and SCE territories only.

 ** “Package count” refers to an actual count of lamp packages present in the stores for each lamp model. Coupled with data on the number of lamps per package, package counts enable calculation of the number of lamps per store for each lamp model.

As shown above, the most recent shelf survey data collection effort took place in California during Winter 2015-2016. During this phase of research, field staff conducted shelf surveys in 207 retail stores throughout PG&E, SCE and SDG&E’s service territories in California. All CFLs, incandescents, halogens, LEDs, cold cathodes, and HID lamps were inventoried. Field staff collected data on base type (medium screw base [MSB], candelabra/small screw, large screw, GU-type, pin), bulb style (A-lamp, spiral/twister, spotlight/floodlight, globe, tube, torpedo/candelabra, nightlight), whether or not a bulb was IOU discounted, rated life, color lumens, wattage and controllability (3-way or dimmable). Full package counts were also collected for each bulb type.

During the Winter 2014-2015, Summer 2013, Winter 2012-2013, Summer 2012, Fall 2011, and Spring 2009B phases conducted in California as well as the Fall 2012 phase conducted in Arizona and Georgia, field researchers gathered the same data as in the Winter 2015-2016 phase. Earlier data collection phases included the following:

California Spring 2009A. In 76 retail stores, field researchers collected data on MSB A-lamp, spiral/twister, spotlight/floodlight, globe, tube, and torpedo/candelabra CFLs and their incandescent equivalents only (no other lamp types). Additionally, wattage, controllability (3-way or dimmable), and lumens (for CFLs only) were collected. This phase of research did not include package counts.

California Fall 2008. In 202 retail stores, researchers gathered the same data as in Spring 2009A.

California Spring 2008. In 123 retail stores, researchers gathered information only on standard MSB spiral CFLs (non-dimmable, single wattage) between 9 and 30 watts as well as their MSB A-lamp incandescent equivalents. This phase of research did not include package counts.
