We’ve covered standard lighting terms before, but LEDs have a set of terms of their own. The barrage of foreign jargon and acronyms on LED data sheets can leave a lot of people floundering between numbers and flashy buzz-words they aren’t used to. So here’s a short list of 10 important industry terms and what they mean to help you make a more informed decision when you’re picking out your next LED light bulb.

Most of our world is a layered mass of solids and liquids. Stacked on top is a thin layer of invisible gas we call air. While mostly inert nitrogen, air contains the elements needed by almost every living thing and plants use both oxygen and CO2 depending on the day/night cycle. Plants breathe using the stomata, or pores, underneath their leaves. Over time these pores can get clogged by dirt, dust, or other air-borne particles pretty easily. Usually, rain and wind wash and dry the leaves to keep them clean while moving fresh air around them, but in a greenhouse or grow room you have to replicate the effect using ventilation systems and sprays.

This past January, EISA brought us the final phase out of 60-watt incandescent bulbs. But two years ago, the phase out program removed some halogen PAR lamps, T12 linear fluorescent lamps, as well as some less popular 2-ft. and 4-ft. T8s. The T8 700 series fluorescent lamps were just shy of the chopping block on the previous phase out, but were given a two-year extension. On July 14th, 2014, all T8 700 series fluorescent lamps will fail to meet the new minimum energy ratings and will no longer be produced. The new ratings increased the minimum allowable values for lumen efficacy (lumens-per-watt), wattage, and minimum color rendering for each lamp. The 700 series of fluorescent T8s has terrible color rendering (averaging in the low 70s) while the newer 800 and 900 series of lamps deliver more vibrant color saturation at CRI levels of 80-85.

Most light bulbs are made from glass, and glass is one of the most easily recycled materials on the planet. So recycling light bulbs should be an easy and effective way to top off going green when you upgrade to more energy efficient light bulbs, right? Not quite. Each type of bulb is different and requires different considerations for disposal. So let’s take a look at how to properly recycle your old or broken bulbs.

After a month of waiting, none of your seeds have sprouted and you just don’t know what went wrong. In fact, the radicle (the root tip which appears first) hasn’t even shown and you’re starting to think all of your seeds have gone bad. While infertility is a possible reason, let’s hold to hope that it’s something else. Seeds can remain dormant for multiple reasons, but the typical cause is that conditions have either not made the outer shell permeable or the internal embryo hasn’t yet developed.
