Long Drop LED Pendant - Smoked Glass Shades

Do these come with a cool white bulb? If not is it an option?
These come with 3000k lamps included. You could purchase MLG9LED7 in addition which are 4000k.

We are looking for lights for a large entrance hall with a large drop. Looking at these I wonder how much light they actually give off ?
The smoked glass can cut out around 30% of the light, so more practical light comes through the bottom. In a larger space you could try using LED lamps that are brighter but you would not wish to have them so bright that they are a cause of glare. So, if the entrance hall is around 25sqm use four additional spotlights, under that size you could use the 7-light pendant alone as long as the hall does not double as a place to read a book. 5-light is for 10sqm or less.

How many bulbs are included in one smoked glass shade?
Each glass shade contains a single bulb.

How long can the drop be? I need the chandelier to be 500cm long. Is this possible?
It is not possible to have this fitting with such a long drop - we suggest looking in our long drop fitting section for suitable fittings.

Is it possible to have the exact size of shade?
Each shade measures 130mm x 95mm x 130mm.

I am thinking of purchasing this light for a conservatory which has doors to the garden. Would there be a risk of the shades smashing if there was a draught through the room - how rigid / stable are the wires? If a shade were to smash would it be possible to buy a replacement part? Also can they take a 6w bulb? - one of the comments is that the light is not that bright.
The shades are glass and relatively small. It would take a strong gust to make them move and as we assume they are not being installed at the same height the chances or breakage are slight. The mains LED lamps supplied are a relative new technology and their life and light output will only improve in the next few months and years. We think the light output is sufficient, if you disagree we will source a higher output lamp for you.

What is the width of the ceiling rose with this light?
The 5 light has a 430mm diameter. The 7 light has a diameter of 500mm.

Is this light dimmable?
This fitting comes with non dimmable G9 LED lamps, but if you were to source your own lamps that are dimmable this is able to be dimmed.

Is this product suitable for a ceiling that slopes, or will it look odd?
Square and rectangular ceiling plates can look odd on a sloping ceiling whereas round plates work okay. If your ceiling is less than 45° pitch it will work (and look) well.
