REPL BULB # FS-227 14V/28V

Bulb arrived on time and worked perfectly. Was in a plastic bag and could have been crushed so one star less for packaging. Note clips that held old bulb had oxidized and needed burnishing before inserting and may have caused the failure. bulb.

Mine arrived and worked perfectly. I suggest removing the entire strobe and removing and replacing the bulb inside at your bench. Use gloves and dont touch the bulb with bare fingers. Oils shorten the life. Sometimes the clips have to be burnished to make good contact after years of use. I have seen a strobe bulb fail due to a slight resistance arc and heating at the clip. . Why not 5 stars? Bulb should be in a box from the factory not just a plastic bag - or wrapped in foam then in the plastic bag.

Not sure if it’s a bad bulb or the unit itself but it didn’t work. So I can’t comment on the quality. The packaging was fine and legs weren’t broken.

See my earlier review from March 2020. It is one year later, and my plane might have flown 70hrs in that year, and the bulb already needs to be replaced again. I will be replacing the entire beacon this time. Not wasting any more time or money on this inferior product.

Had to replace the lamp because one of the legs broke. When the new lamp arrived, the center leg was already broken off. I wish I could find a replacement lamp that was better quality.

This is the worst quality bulb ever, do not buy a light that requires this bulb. Grounding lead separate from bulb and has an extremely poor quality solder. I have been using these bulbs for about 3 years and completely regret buying the unit. They also come in a ziplock bag and not a box so have had a few that were damaged in shipping.
