Yes, if you rewire the insides, like I have done, to make it always-on when plugged in. No soldering is necessary, but you'll need to move one wiring from the mains plug on the inside so it matches up to the posts on the ballast. It would take me all of five minutes if I were to do it again.
I gave the light to a friend so I can't answer that question for you. I do suggest, however, you check out the cost of replacement bulbs as ours burned out after a couple of weeks and a replacement bulb costs twice what the unit cost.
In my case, nothing! I tried to get a hold of the company a few times to warranty the lamp, and they never responded. In my opinion the warranty is a total fake and the customer service for this company non-existent. I would pick another lamp and even consider paying a bit more for something of a better quality.
yes you can replace it. But I have used this product and I still have the bulbs in good condition. Also it comes with additional bulbs for replacement, so I don't have to worry about that. Sorry but I don't know where you can purchase it in your country, but amazon has the replacement bulbs for this machine . You can buy it through amazon.
