In this study, we performed a market trial of off-grid LED lighting products in Maai Mahiu, a rural Kenyan town. Our goals were to assess consumer demand and consumer preferences with respect to off-grid lighting systems and to gain feedback from off-grid lighting users at the point of purchase and after they have used to products for some time. Key findings from this work include the following:

  1. There was modest demand for the lamp products available through the Market Trial, with 23 systems sold to 164 shop visitors (14%) over a period of 9 months.
  2. People preferred the performance and features of lamps designed to provide room lighting over those that were perceived primarily as task lights, despite the higher price of the former products.
  3. One-quarter of the purchasers lived in electrified homes, two-thirds of whom retained the lamps in their home while the remaining used them in their non-electrified place of business. This suggests that people in electrified homes still see considerable value in off-grid lighting for use during power outages or other circumstances.
  4. When given an option to purchase the grid-rechargeable LED lamp at a cheaper price without the solar charger option, 100% of the purchasers paid the higher cost to purchase the solar charger. This result contrasts with previous findings from prior work reported in Lumina Technical Report #3; it should be noted that the sample size in both cases was relatively small.
  5. In follow up surveys completed a number of months after the initial purchase, 86% of buyers reported that the LED lamp fully replaced a pre-existing kerosene lamp. The remaining 14% reported that the LED lamp partially replaced a kerosene lamp.
  6. Six-months after the start of the trial, the people who purchased LED lamps reported using the solar option to charge their lamp more than 90% of the time.
  7. None of the purchasers of the LED lamp products reported significant levels of dissatisfaction with their lamps, and none elected to return their lamp for a full refund when presented with this option approximately six months after they had purchased the lamps.
  8. Reasons for low sales appear to include a combination of contextual factors combined with suboptimal product marketing, including:

9. Market trial tests should include a diversity of product types; it is further important to anticipate and eliminate potential, and often unforeseen, impediments to sales.
