Review: 100% recommend and great customer service! - These bulbs have saved me a ton of money and are easy to install. I do not experience the issues that others have cited with needing to break tabs, etc. I have been using these bulbs in my Viqua for over 6 years an never had a problem until the second bulb (in a two-bulb pack). The bulb burned out in 79 days. I contacted LSE Lighting and explained the situation. They sent a replacement in less than 24 hours, after responding in under 2 hours. Now that is customer service! Highly recommend.
Review: Poor fit - Just Replaced light, if I had done it in the return window I think I may have actually returned them. Too much time wasted on figuring out what the problem was and then customizing the plug portion, which should have took all of five minutes if that. Just don’t feel they were worth the money saved, not to mention let’s see if they last their one year. In fact on first install, light was blinking green finally turned to red. Pulled out and reset, hoping when I go back down to the basement it’s still green. The problem is the pins are very inaccurately set into place I used the old bulb (Vique) to take measurements and reset very carefully with needle nose pliers. Apparently the two pins should be 1/4 inch center to center I had to bend them in a hair and I used a spark plug gap gauge to reset the pins inwards towards the center plastic Finn. And as close as I can tell because the pins are set into the plastic mold out of position the plug is not 100% properly seating, but seating enough to work, hopefully. Oh and I also had to snap off the two outer fins adjacent/parallel to the pin sides. they seem to be molded slightly smaller in words than the original. So as close as I can tell to make a very long story short the plastic plug housing and pin set up is totally out of whack as to measurements.
