compare the yield of bell peppers grown under lights manufactured
by P.L. Lighting Systems and Bell Lighting fixtures.
Summary of results (view full report below for details)
- P.L. 400w HPS light:
- Produced 1 bell pepper per plant approx. 1.5”
- Weak plants, sparse foliage
- BL LF400w HPS fixture
- Produced 4-5 bell peppers per plant approx.
- Healthy, strong plants.
- (Note: The BL LF250w fixtures, in equal numbers to the
P.L. 400w fixtures, produced the same yield as the P.L.
fixtures while consuming 37.5% less energy).
