Assessing Grow Light Efficiency: An Experiment Comparing DIY LED and CFL Lights

In the fertile landscape of indoor gardening, we might readily associate the sun with the caliber of our cultivated produce. Yet, as we uncover in this fascinating exploration and comparison of DIY LED and CFL grow lights, the sun might have quite the mighty rival. We document an engaging experiment by SSFamilyDad, where he scrutinizes three types of grow lights under the demanding gaze of hard-to-please Roma tomato plants.

Our tale commences with Grow light 1, a 6500k 7020 LED strip light that offering moderate growth. Grow light 2, a ‘Cool white light’ using 5630 LED strips, disappoints with lackluster performance, due, it seems, to insufficient power intensity and an unsuitable light spectrum. Rising against its predecessors, Grow light 3, an FCL using 8 CFL bulbs at 6500k/23watts each, emerges as the champion, outpacing the sun itself in fostering superior growth.

Introduction

Embarking on the quest for indoor gardening nourishment, we delve into the mysterious labyrinth of grow lights.

Delving into myriad DIY LED grow light projects proved enlightening, illuminating the potential for LED lights in indoor gardening.

Can we actually construct a cost-efficient grow light utilizing LED strips? That’s the query several of you have posed in the recent weeks since we released the preliminary grow light build video. We’ve performed some upgrades and testing, and we have some fairly satisfactory initial results to share.

We commenced six Roma tomato plants and placed them in like pots all concurrently. We also raised an extra one and placed it near a window. We positioned the three grow lights at an identical height from the plants and using the same timer. The grow lights specifications are listed below –

Grow Light 1 – This is the light we fabricated in the first video with the addition of one improvement. To increase its effectiveness, we incorporated a 6500k 7020 LED strip. The duo of strips we utilized can be found at these links –

Outcomes –

Grow Light 1 – The growth generated by this light was quite underwhelming; however, it was adequately efficient to keep our seedlings healthy. But it didn’t outperform either the CFL light or our sunlight control.

Grow Light 2 – This light was responsible for the weakest growth among the three lights. This light lacked the power intensity or correct light spectrum required for optimal growth. Nevertheless, it enabled things to grow and stay alive, albeit not very effectively.

Grow Light 3 – This light exceeded the performance of the other two lights, and the yielded growth was even superior to the plant we positioned near our window. We are ecstatic with our old CFL bulbs that have been running strong for more than two years.

This was a preliminary test to placate those who’ve been inquiring about them. We plan to construct more LED light fixtures using various LED strips, and then conduct a final test to see if we can achieve superior growth from the LED strips for lower power consumption and upfront expense. If not, we’ll return to the CFLs!
