Question: Is it possible to buy a replacement electrical switch for this lamp?
Document: Overall very impressed with this lamp. It is well made and the three lighting options are awesome! I would buy this again for sure.
Very solid, high quality lamp. Mounting bracket is made of metal, very solid. Haven't used the lamp extensively yet however it is well built and provides great light. Would buy again.
I bought this lamp to paint by, but have relocated it to my home office because the light mix is really amazing for working on just about anything. I like the flexibility of the arm and the fact that it stays in place when you adjust it. A great buy.
When I plugged the first lamp in, it worked perfectly. Excited, I plugged the next one in and was disappointed to discover that the circular fluorescent was defective. I luckily ordered a spare at the prompting of some reviews I read before buying, so my light works. Although this wasn't a &#34;break it&#34; for me, the replacement bulb  does cost $10.00+shipping...so keep this in mind when ordering.
Love this lamp! This is a quality swing-arm with solid clamp and very stable arm. Love that it takes a regular bulb and has a flourescent bulb also. The flourescent bulb is hard to find though and you will probably have to buy one on Amazon. I went to Home Depot and could not find anything similar. The light is a cool white so I paired it with a Cree LED &#34;daylight&#34; bulb and they are very close in color temperature.
I love this lamp! It large and has a good reach. I was reluctant to buy it because of the price, but now I'm glad I did. I'm a very particular person. I love products that are functional and work as though an experienced engineer designed them. This lamp is both.THE FRAME:It's made of 1/2" x 1/2" square steel tubing. It has (2) four-arm plastic knobs that can be used to adjust the tightness of the articulating joints.
Good light it works well but the circular floresent bulb is a 25 watt so when it burns out in a year you can not get a replacement.I would suggest passing on this light and getting something that is fixable.
This now illustrates that since the product page describes one item and specifies part numbers for another you can receive both depending on who you buy it from. Sale Stores, by the way, sells the Alvin unit.
I really enjoy the dual-lighting thing: I can have my Giants Stadium florescent blitz when I need to close down the irises for sharp focus on tiny objects, and with a flip of a switch, I can have a nice soft supplement via the incandescent (a 15W clear bulb).
having 2 different types of light, flourescent and incandescent in one fixture is a bit disconcerting...It sends out a very odd looking light...It is replacing a very nice bright Halogen that I had for years but the switch broke...Hope I get used to it..Feels like good construction but the light is just weird
Answer: yes
