Question: Does this bulb require a special ballast to turn on or can you use it on any existing light socket?
Document: This appears to be a good replacement bulb for a 70W sodium light fixture. Sodium lights are reasonably energy efficient for the amount of light produced. They should last for years...my old ones are in the 5-10 year range of use. If this bulb does not withstand the elements and/or longevity, I will update my review for reference.FYI: It's important to use the correct wattage as specified on your light fixture.
I ordered a 70w bulb and was charged for a 70w bulb but I was sent a 100 w bulb which was too big and I couldn't use it so I had to return it.
The light I received looked nothing like the image. The image depicts a narrow base, but the light I received had a fat base and a large taper so it would not fit my fixtures.
Works perfectly in my exterior security light. The light emitted is amber in color so it's easier on the eyes when looking towards it on a very dark night. Arrived on time and packaged securely. Costs less than local stores.
I have 2 lights like this in the front of my house and they throw off enough light to light up my neighbors houses too so its a safety thing and there long lasting this place is a good buy and cheaper than some of the others that want to gouge you cant go wrong getting your bulbs from here.
My old bulb was having a little trouble starting up, but this replacement works fine. Looks just like the picture.
I haven't had the bulb for very long, but so far so good. Good price and it works great. Just have to see how long it lasts.
Good price for this sodium bulb for my barn-beats all local stores. It looks just like it was made in the same place as the expensive bulbs.
Saved 60% over price at big box (returned). Works great. Glad I tried this bulb, despite some iffy recs and tgtbt pricing..
Over the years of buying 1000s of bulbs of every type in my profession, I have learned that there is very little noticeable difference in life and performance. Keith L
