![]() ![]() They can work with less than 10 watts on them, but they might buzz or worse, flicker. Hera has told us that their 60 watt 12v transformers require a 10 watt minimum load to perform properly. Secondly, if your lights are in a home or office, thus operating from the Hera 12v halogen transformers, here is your word of warning. To be more realistic though, if you have this bulb on 6 to 8 hours a day, 5 to 6 days a week, expect that it will last 4 to 5 years, but still cost you under $1 a year to run it. At that rate, they are also estimating your annual energy cost of using this bulb 3 hours a day to be about 30 cents. The back of the package estimates a 9.1 year lifespan when used only 3 hours a day. ![]() But this $7 LED bulb from Home Depot is rated for 10,000 hours. That was a great bulb and we miss that one. And we did have a Xelogen bulb (a Xenon bulb to use in place of halogen), those had ratings of 10,000 or even 20,000 hours. The premium halogen bulbs were rated for 4000 hours. ![]() In comparison, the economy halogen bulbs that we use to offer were rated for 1000 hours. The front of the package does say 12v, and the estimated life is approx. So it will be bright, but a little less bright than the halogen. A 20 watt halogen bulb is usually about 300 lumen. Yet at 2.5 watts and being 12 volt, it will NOT be as bright as what you use to have with your 20 watt halogen. It implies it is the substitute for a 20 watt halogen. On the front of the package it clearly says G4. This is the packaging of the bulb I bought. I did buy one, so I could write this blog post and offer more helpful info. A nicely sized LED bulb to take the place of the glass halogen bulb. But back to the sparkling little G4 LED bulb that jumped off the shelf and right into my hand. This is true of Tresco, Mepla, and other companies that made under cabinet lighting, and used G4 bulbs. You must get a G4 bi-pin bulb to fit in the Hera halogen lights. So when you go bulb hunting and see G6 and G8, those will NOT fit in the G4 sockets that Hera used. Thus the two little pins that push into the socket. What G4 represents is that the bulb is bi-pin. It is important to us to continue to help our customers, so we wanted to see what Home Depot had. We have been slowly selling off the overstock over these last many years and just recently sold the last of our G4 halogen bulbs in 10 watt and 20 watt. All lights and parts for the lights, including bulbs, were no longer made and offered from Hera. ![]() Hera discontinued everything halogen in August, 2015. We went to Home Depot to see if G4 halogen bulbs were even still available. As technology continued to expand, so did solutions. So we feel, the LED pin was a failed experiment. ![]()
