Efficient "Bar" style LED grow light, high output, low temp LEDs (ideal)
I purchased this grow light bar for a hydroponic indoor lettuce growing project. I wanted to test this product against a few others I have ordered (also on Amazon). The light arrived very quickly and was packaged decently for safe transport. This 'Canagrow CG-400 LED' grow light bar utilizes newer LEDs indicated by the high μmol output. Measuring a light by lumens is for humans. Plants should be measured by μmol/PAR to equate the PPFD . This specific bar LED actually achieves the stated μmols that is advertised in their marketing when measured with an Apogee MQ-500 Quantum PAR meter. These type of LED grow lights have come a long way since inception, therefore it runs very efficiently. This can effectively replace a 200w-300w Sodium Halide grow light (but coverage of this light is recommended for a 2ftx2ft area rather than a 4x4ft area) while only pulling roughly 50w from the wall and delivers a more even coverage than a bulb+reflector which suffers from spotlight intensity. You also benefit from an absence of heat buildup due to the LED efficiency. This is ideal for a grow tent, cabinet, or indoor growing environment. Additionally modern LEDs have 10x+ the lifespan of a bulb while never diminishing in intensity. This light has a plexiglass or polycarbonate cover plate over the LEDs, giving this light a "water resistant" rating. It seems that the plate could easily be removed for cleaning although I did not have to remove it. It is lightweight and can be mounted with the included clips and wire. The bar can be controlled by an external timer (not included) and does not require an On/Off switch as some other lights require. I have had this light for a few weeks and it is producing ideal growing results with my hydroponic lettuce project, therefore I do recommend this for others. Read more
