Question: These lights are sold in 4 different beam angles: 10, 20 30, and 60 degrees.  Which angle do these have?
Document: At a fraction of the cost per bulb - i can recommend. Same problem with these as well as the ones that cost more - you are lucky if you get 1/4 of the hours advertised. I am using outdoor in 10 volt lighting - I have to replace monthly.
You get what you pay for. These lights just don't last. Less than 4 months and they burn out. Yes they  are chap, I will pay a fee more dollars for low voltage lights that will last longer.
These 12 volt halogen bulbs were used outdoors for landscape lights. They were less than $1 each compared to about $4 at a store. They work as advertised with good light, but don't know yet how long they last. Great value
I use for outdoor landscaping lights. I have purchased the expensive version of these bulbs, the average priced bulbs, and these which are the least expensive I've seen. Honestly, they pretty much all work the same. For some reason, everything lasts 4-8 months and then need to be replaced. These last just as long as the other versions, look the same, and I've had no trouble. They are warm toned vs. cool toned.
I have used two different types of bulbs from CBConcept and have been extremely pleased with both of them. Same quality as the more expensive brands at a much cheaper cost.
I bought 60 of these to retrofit a building with 12v lighting. These were sent to me WITHOUT lenses. I am sad that they would send the wrong item. I have  lot of a faith with Amazon but if they run out of an item they should refund my money instead of sending something else.
I purchased these 20-watt bulbs as replacements for the original 20-watt bulb which burned out in normal use. I purchased 12 replacement bulbs through Amazon for the price of 2 replacement bulbs from the local brick and mortar store. As long as they give me the useful life of the original bulb, I will be more than satisfied. These CBconcept bulbs come with the added feature of a sealed glass lense, that the original bulb did not.
These bulbs work flawlessley..... Very happy not having to spend $3-$4 per bulb at the store for the same bulb. I will be ordering sll my bulbs from here from now on
I'm THRILLED with these light bulbs at this price. What a bargain! I used them to replace the bulbs in myPossini Euro Bubbles 13 3/4" Wide Ceiling Light Fixture, which needs five of these bad boys. My only complaint is that they have a pink tint around the edges, which the previous bulbs did not have.
I can't believe I've been paying $4 apiece for replacement bulbs for my Malibu fixtures all this time. I was skeptical, getting twelve bulbs for the price of three or four, but I'm glad I did. They're at least as good a quality as you get from Lowe's or Home Depot, with the same warm light, but for a much more reasonable price. I'll be buying a lot more of these, I'm sure.
Answer: yes
