Great for a cold shop
By R. D Johnson
I have old T12 fluorescent fixtures in my garage shop with the old magnetic ballasts that don't work well below 50 F or so. Furthermore, the T12 lamps are now hard to find, for better or worse having been regulated out of existence in the U.S. this July 2012. As my fluorescent tubes were getting old, I started investigating the cost to upgrade to newer electronic ballasts and T8 style tubes. That's when I discovered that for not much more I could buy these LED tube lights instead. So I bought a pair as a test.Overall, I'm very pleased. The re-wiring turned out to be much easier than I expected. These lamps are single-ended (hot and neutral pins are on one side of the lamp), and that worked out great with the existing wiring in my fixtures, as I document in the images I posted with this review. It only took about 15 minutes to rewire the fixture, and most of that time was spent with a volt-ohm meter verifying the original wiring layout was what it appeared to be. I've ordered more tubes, and expect the rewiring of the remaining fixtures to go much faster. Naturally, your fixtures may be wired differently, so don't follow what I did verbatim. Verify the two contacts on the tombstone connectors are not shorted together, as you need hot on one side and neutral on the other. It also goes without saying that if you aren't comfortable working around electricity find someone who is to do the rewiring for you.Operationally, these lamps work great. There is a short delay of a second or so when you flip the light switch before the lamp turns on. However--unlike fluorescents--the tube is immediately at full brightness. This morning the temperature in my garage workshop was just above freezing, and with a flick of the light switch the LED tubes were glowing brightly. Only about half the fluorescents even turned on, and those that did were dim and flickering and took a good 10 minutes to warm to full brightness. Even then I'd say the LED tubes were brighter, while consuming less than half the power. Wonderful. These LED lamps are rated down to -20 C, and at that temperature I'll be by the fire and not in the shop anyway. Although the instructions state these lamps are intended for fixtures without a diffuser cover, they work just fine in mine with the diffuser covers installed, with no noticeable decrease in brightness and a slight lessening of the more 'directional' light cast by the LED lamps.The lamps come in T8-sized cardboard tubes with the instructions rolled up inside, so if you can't find the instructions bang the cardboard tube until they pop out. It's hardly worth the effort though, as the instructions don't tell you much that you can't figure out just by looking at the lamp. I like the natural white of these lamps (hence the NW in the part number) as they don't appear to have much color tint to them, either to the warmer (yellow) or colder (blue) side. Note that the suffix gives the color temperature (WW warm white ; NW natural white ; WH (cold) white). The only remaining question is longevity, and I'll just have to wait and see about that. However, LED prices seem to be dropping regularly, so with any luck when these tubes do go out hopefully their replacements will be even more affordable.

By Dad with girls
This light is everything it should be, it comes with it's own instructions so it is easy to rewire the old fixture, it lights up wonderfully and I basically have no complaints. Be aware (I already was) you have to rewire the light fixture to bypass the ballast and put the hot and neutral on one end of the tube, this one has instructions, albeit in broken english but understandable, and clearly marked hot and neutral pins so it was a simple task. (I got a warm white tube that had no instructions or H/N labels and it was configured differently so that turned out to be difficult and dangerous) But this one is great.

By C. Saito
fairly easy to instal, turns on quicker than the 2 Florescent lights is replaced (when its cold ) and is as bright or brighter than the 2 40 Watt bulbs combined, highly recommend - if you have some understanding of wiring - you will need to rewire the fixture
