The Shengsite 75 watt plant grow light (model CLPP) was ranked 28 out of the Amazon 100 best-selling plant grow lights and had an overall review rating of 4.5 out of 5. At the low end of our price range, it was priced at $19.99.1
That price alone was a big part of our buying decision, as it was at the very bottom of the range of LED plant grow lights we found that (claimed to be) powerful enough for our application.
It is a Red/Blue spectrum plant grow light with 250 total LEDs, with a red:blue ratio of 3:1. This works out to 186 red LEDs and 64 blue LEDs. The provided spectral analysis (Figure 1) shows very strong spikes between 460 and 470 nanometers in the blue portion of the spectrum and between 660-and 670 nanometers in the red portion of the spectrum. Light output in other areas of the spectrum is negligible. LED lifespan is rated at 50,000 hours. Shengsite offers a 12-month warranty and a 60 day return period.
Circular in shape with a diameter of about 13 inches (0.33 meters) is what we would refer to as a “round panel” plant grow light, which should create a circle of light beneficial to your plants. This is not optimum for the long, narrow shelf design of our growing area, but would work well for a large single plant in a corner of the room, or a small group of plants on a table. It is constructed of ABS plastic with an “aluminum coating.”
It claims to have Photosynthetic Active Radiation (PAR) of 398 micromoles (μmol) across a 0.25 meter circle (about 10 inches) at 0.2 meter height (about 8 inches). At a height of 0.5 meters (about 20 inches) it will project 215 micromoles of PAR across a 0.64 diameter circle (about 25 inchs). We are presenting these numbers as the company does, but it’s not clear what they mean by using “PAR,” as it is a type of radiation, not a measurement thereof.
Photosynthetic Active Radiation defines the type of radiation needed for photosynthesis – light between 400 and 700 nanometers is Photosynthetic Active Radiation. The company’s use of the measurement “μmol” (micromoles), which is a measurement of photons of light, is normally used with Photosynthetic Photon Flux Density (PPFD) which is a measurement not of the amount of light produced by the light, but the amount of photons hitting a specific place over a specific time period. It is normally measured in micromoles per square meter per second (μmol/m2/s). It makes sense that is what the company is trying to express, so for comparison, we will assume that is the case. We recommend always taking these readings with a grain of salt, because companies will often just measure the light intensity of the LEDs in the center of the circle, ignoring that light intensity will fall off towards the edges.
We measured the light output in lux with our Reed 8140 LED light meter. It is equipped with filters to accurately measure color LEDs, but, unfortunately, it can only measure one color at a time. So we measured the output of the Shengsite LED plant grow light with both red and blue filters (Figure 2). Engineers at Reed suggest creating an average of the two readings for an accurate reading in lux. There are a number of calculators online that convert lux to PPFD.
