## Description

OSRAM 75173 SubstiTUBE Instant Start LED T8 lamps are a 4-foot, energy saving alternative, designed to replace traditional fluorescent T8 lamps. These shatterproof LED T8 lamps contain no mercury, provide instant light and a uniform light distribution. Engineered to operate on existing instant start electronic T8 ballasts, these lamps minimize labor and recycling costs. Because the SubstiTUBE IS LED T8 is not affected by switching cycles, the use of occupancy or vacancy sensors can now be installed with the existing instant start ballasts for optimal energy savings.

Review: THESE BRIGHT LED T8 BULBS WILL LAST UNTIL 2056. ARE YOU KIDDING ME? - My basement and workshop are marginally illuminated by twelve twin-tube fluorescent shop light fixtures. If the ballasts don't burn out first, the lamps eventually begin flickering and turning black on the ends accompanied by diminishing light which necessitates maintaining an ample supply. Changing these tubes has been a pain for 35 years. It's long been known that flashing lights can cause seizures in some people. I don't lose awareness when a tube starts flashing but certain muscles do seize up real tight when it happens. Standing on a ladder and holding a chain-mounted fixture steady with one hand while inserting and turning the tube with the other hand is an art that's hard to master. I was both interested and skeptical when desertcart offered me this expensive LED T8 bulb. However, it was perfect timing as I had recently installed two new twin-tube T8, 32W 4100K fixtures and was cursing those responsible for making me work under such pitifully DIM lights. Life is all about learning curves. I crashed and burned on my first attempt at installation as all the light was focused upward into the fixture. Although unmarked, these tubes have an up and down side just like a light bulb and I had inserted the wrong prongs in first or else twisted them the wrong way. Once the tube was inserted correctly, I was amazed at the INSTANT brightness. With this much light, I don't care what color it is. I've never seen this much illumination from any fluorescent tube in the 32W - 40W category. Having said all this, I do have one major problem. I need 24 of these LED T8 tubes which would currently cost $420.00 and last 41 years. Why do I need a 41-year light bulb? Are they heirlooms or what? In 2056, our indoor light will be emitted from paint and wall paper. When CFL household light bulbs first hit the market, they were expensive and advertised to last 7 years. I purchased several of the top brands. They were all about the same, PITIFUL! I would flip a switch and then stumble in the dark for a minute waiting for the light to appear. The absolute worst of the bunch was the enclosed spiral bulbs. Some didn't last a year. The packaging boasted about how much money these magic bulbs would save me. I have yet to have one last more than 2 years. I felt like I was a gullible kid again getting ripped off at the county fair trying to win a Teddy Bear for my Honey Bear. If Sylvania will cut both the price and lifespan by 50%, I'll buy what I need now. 24 LED T8 tubes for $210 that will last 20 for years sounds about right. I can live with that. eheheh Never having to stand on a ladder again to change a shop light bulb does sound too good to be true. That's what worries me. If it sounds too good to be true, it usually is. As the old saying goes, "Burn me once, shame on you. Burn me twice, shame on me." At the moment, I couldn't be happier with this LED 32W T8 bulb. I wish I had 23 more. Unfortunately, I can't read the future. I've got about 20 new fluorescent bulbs on hand. Some are outlaws that are not made anymore. It will take about 3 years to burn through the bunch. If this LED T8 bulb is still burning brightly at that time, I'll be a semi-believer. Until then, it's wait and see. In 3 years, I suspect the price of LED T8 bulbs will drop by half. If I haven't fallen off a step ladder and killed myself by then, I'll go shopping for a truck load. Let me get this straight. If the average lifespan in the USA is 78 years, that means that any purchaser over 37 years old will probably not live to celebrate if these T8 bulbs do last 41 years. Go far for the brass ring. You only live once ... albeit not long enough.

### ⭐⭐⭐⭐⭐ This Baby is BRIGHT.. No Sensitivity Problems Either!
*by C***L on January 6, 2015*

In our laundry area, we have a single T8 fixture. Housed in that fixture we have always had Philips Colortone 40watt T8 bulb. The color range is listed as natural sunlight and the lumens are 2200. The temperature is 5000K. This bulb type has lit up the area nicely allowing us to see what we are doing quite well. I always thought it was a pretty bright light - until we put THIS bulb in. WHAT IS THIS BULB LIKE? Not glass like florescent bulbs are, this is made of what appears to be a pretty sturdy plastic. The ends go into the fixture just like any other T8 tube. It comes in a box with basic information on it. HOW DOES THIS BULB PERFORM? I could not believe the difference in this bulb when I put it in. What I thought was a fairly bright light turned out to be quite weak compared to this bulb's output. The increase in light is about 2 1/2 times that of the other bulb. The visual appearance is a bit more on the yellow side than the previous bulb, but that was not unexpected. I am very sensitive to lighting, so I tend to notice things that others don't even notice at all. The visual clarity is really nice- but it is a different type of light than the florescent bulb. This takes some time to get used to, as it different enough to notice, but I have not had any problems with it so far affecting me in a negative manner. Some lighting does that and I can not use it. I have to be careful with light bulbs as I can get dizzy or headaches from certain bulbs/lights. As I leave the light on, it does tend to intensify just a touch as the LED's warm up. The light turns right on without the blinking factor. I didn't notice any significantly warmer feel to the bulb itself (as in touching it) over what I would expect. THE BOTTOM LINE This bulb is not cheap, but it does claim to last a very long time. The lighting offered from it is a touch warmer than the 5000K sunlight temperature of lighting we had in the room, but it is a LOT brighter, making it easier to see in all areas of the room. My only concern would be over time the plastic getting cloudy and or yellowing from age and use. Only time will tell about that. For now, it is a great addition to our laundry area. It does say that it can be used in damp areas (just not outside in the elements) so it is good for basements and such. UPDATING As with all of my reviews, if something happens that causes me to need to offer more information or updates on performance, I will update on this bulb.
