First of all one must choose the right wattage for the room. Medium to large modern rooms usually won’t need more than 200 to 400 watts to provide enough light, in case it’s needed. A useful formula to calculate the right amount of watts needed to provide what is called “general lighting” is multiplied by 1.5 with the length and the width of the room. Going just a tiny bit overboard with the wattage could be useful, if you decide to use dimmers, so that you’ll get a better control of the lighting projected by the chandelier.
As chandeliers generally have quite a few modern lighting fixtures, it’s best to use the small 40W economic non incandescent light bulbs, as they offer a very good price/performance ration. If using smaller fixtures, such as the ones used in bubble chandeliers, one could go even lower, down to the 20W range. You just have to take into account that even if you use a dimmer with small wattage light bulbs, they’ll get quite hard to control and you’ll need a good hand to set it just right.
Another thing to look after when selecting a bubble chandelier is its size. The general consensus in picking chandeliers’ sizes is: if you take a room’s footprint in feet and divide it by 5, chandelier’s size should somewhere around that number in inches. So, a room 12 by 12 feet would require a 25 to 30 odd-inches in size chandelier. It’s tantamount not to overdo its size, as a chandelier too big for the room will overpower it. Also, too small a chandelier in a generous-sized room will look odd and isolated; not a good thing.
One good thing about the recent developments in the modern lighting industry is the appearance of the bubble chandelier. Not as imposing as their older counterparts, bubble chandeliers allow you to circumvent the aforementioned limitations in size and go wild. Although you can buy a large assortment of ready-made bubble chandeliers, one can also easily DIY them, and make them exactly fit the room aesthetic.
When hanging a chandelier, one must pay close attention to the fact that due to its long reach, it’s best to hang it at least 8 feet above the floor, preferably more than 10 feet. So, unfortunately, not many blocks of flats offer you the possibility to use chandeliers. Although usually placed in the center of the room, in modern times an offset positioning might be in order. But great care must be had in mind when doing this, as, aesthetics aside, you have to ensure that it’ll do its actual job: provide a pleasant and adequate light for each and all.
