Our range of grow lights is exceptional and, right across the board, it represents this form of light technology at its very best. We’re proud to recommend all of them. But the LM301B with Samsung diodes is worthy of a special mention. It’s one of the shining stars in our LED Grow Lights selection and here’s why.ContentsSpecs of Samsung LM301BPhenomenal efficiencySpecs of Samsung LM301B To start with, for the more technical minded among you, here are all the facts, figures and features of the 400W Samsung LM301B:High Energy Efficiency with 2.7 umol/J400w Power Consumption Light Coverage: 6ft x 6ft (Veg), 5ft x 5ft (Flowers)SAMSUNG LM301B & Osram Diodes - (660-665nm, 3000K, 5000K, 730nm)Dimensions: W60cm x D48cm x H5.9cm2 x Meanwell ELG240 Driver Driver with Full Dimmable ControlPhenomenal efficiency Now that we have satisfied your more technical cravings, let’s take a more in-depth look at this LED grow light. One of its biggest selling points is it phenomenal efficiency.The power of the ultra-efficient 400W Samsung LM301B is comparable to an 800W HID Grow Light. But with a maximum power of just 400W, an incredible amount of Photosynthetically Available Radiation (PAR) is generated in comparison to its Photosynthetic Photon Flux Density (PPFD) footprint - PPFD refers to how much light reaches your plants within the PAR region or the number of photosynthetically active photons that fall on a given surface each second.With a 5ft x 5ft canopy (4ft by 4ft for flowers), this indoor grow light boasts incredibly widespread Samsung diodes to maximize growth potential, even at a low roof height. Thanks to this low-profile panel, the indoor LED grow light is able eliminate shadows which usually hit the most photosensitive regions of your plants, while also allowing for flexible indoor growing. The 400W Samsung LM301B combines the most efficient LED diodes with two Meanwell ELG 240 drivers for high-efficiency conversions and yielding. Because of this it is ideal for commercial use but we also sell a lot for domestic hydroponics setups, and it’s easy to see why. They’re completely fan-less, and are cooled using passive heatsinks which have extremely low heat output, with the added advantage that they’re 100% silent. Indoor LED grow lights in New Zealand don’t come any better. In fact, if we were to nominate a perfect grow light then this model would come very close. We’d be delighted for you to contact us and ask us why we have formed that opinion.
