Diamond Cut LED Menorah with Exciting Lighting Options 10.50" Electric Hannukah Menorah

Can I light one by one lamp? So every day one more

What color is this? It says blue in the description, but looks like it is black and silver in the picture. Thanks!

menorah relights by itself after I shut it off .I have to remove a battery for it to remain off. Is there a way to resolve this?

do the bulbs require replacement
