two-bulb ballast

do you need to replace both fluorescent bulbs or can you use only one LED bulb?
Asked by: LCpalmbay
Yes, you need to replace both the fluorescent tubes, but once you have LED's replacing just one is OK.

InstantFit 4 ft. T8 14.5-Watt Daylight (5000K) Linear LED Light Bulb is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Now this is how an LED replacement should be. This one actually made me excited, because it was a drop in replacement. I have had LED 4 ft lights that I had to modify the fixture to remove the ballast. They worked well and removed the ballast, however, these drop right in. They are compatible with fast start too.

Rated 5 out of 5 by from very bright I have never been a fan of fluorescent bulbs (indoors) and this LED bulb will use much less electricity and is a cleaner light-- I use in my garage.. The only problem is these bulbs need a ballast that will accommodate T8 32W bulbs (mine was T12 40W which didn't work). I bought the correct ballast at Home Depot (a 2-light) and am very happy with the new light. You can use fluorescent and LED in the same ballast.

Rated 5 out of 5 by from Picture Perfect These lights are great, but I have a few words for everybody. These linear lights do run with a standard ballast, however it must be a 32w/instant start type and on the list of compatible ballast that Phillips online site has. SO, THEY DO NOT JUST REPLACE THE STANDARD LINEAR TUBE LIGHT AS IT MAY LEAD YOU TO BELEIVE. My fixtures were 40w ballast. This is not my first set of linear LED's, as I have four types now and this ballast was only $14, one set of linear LED's required a Driver at $65 on top of tube at close to the same, times 2, so it adds up fast. So, read and go to the manufactures web site and look up all the details as I also found that one brand they (HD) listed the same instructions for all and this is where I got hit with the extra cost of a driver for the LED tubes. My main point is go in with both feet and know what your getting, if I had know up found the extra equipment I surely would of not been heated under the collar X5. If you just happen to have the type oft ballast required already, you are set to remove, replace and turn on. If a new ballast is needed it's a cake walk to replace. Be SAFE is NUMBER ONE in any case. Great lights, all my LEDS of this type are 5000K or higher (DAY LIGHT) and cost to light output is 5 fold over the standard linear bulbs. And it makes everything extra sharp. Of all of them, the 6500k (DAY LIGHT) linear tube bulb is by far the brightest of them all. anything below 5000k and you start into the softwhite light and/or cool light. It's all depends on what you like and for what they are use for, I'm pushing the big 60 and clear, bright light without the glare is perfect.

Rated 3 out of 5 by from INNOVATIVE PRODUCT Phillips has made a T8 linear LED light bulb that replaces conventional linear light bulbs without having to rewire fixture or a special ballast. This LED light bulb is light weight and has a nice design. One negative to this LED T8 bulb is that it flexes when installing it into fixture and makes it a little tough in tight fitting fixture sockets. ( especially if trying to install one handed.)

Rated 5 out of 5 by from Excellent LED Alternative to Linear Fluorescent T8 Bulbs Recently replaced an old T12 fixtures in my kitchen with a newer fixtures that uses 4 T8's. Rather than using fluorescent bulbs, I chose to try the Philips Instafit LED's so that I did not have to worry about removing the ballast. Installation is quick and easy since they install just like a standard T8, just point the lens downward. Yes, they are made of plastic and have some flex, but no more worrying about breaking glass when trying to install these. I chose the 5000k bulbs which light up my kitchen much better than warmer colors, a bit bright in the mornings when you first wake up but things are much easier to see now and no waiting for them to warm up like fluorescents. Highly recommend these bulbs, I plan to start using them at my commercial space as fluorescents burn out. Nice thing is here in the Seattle area these can be recycled for free by electronic recyclers in the area vs. having to pay to dispose of fluorescents.
