Review: I prefer this device because of the independent light source!
Review: Since i received it it was literaly 2 days and not more then 10 clicks and the light bulb burned. This is second lamp that burns. I can be buying hole sets just for few cent light bulb. Can you provide information about the light bulb. Links of where to buy this light bulb would be also good to have because the light bulb included is not reliable att all. Led can do the trick maybe but incandescent light like this is pretty desirable in Gemology because of possibility to check if stones changes colour to different light. So it will be a big plus if you supply the small light bulb. I hope someone reads this and consider this as a solution because ithis is world wide problem. On all desertcart platforms.
