Fire Rated Down Lights

[Spazz]

what make are these bulbs?

If you dont know post the ebay item number - I might be able to find it on google.

Just looking most 4W LED GU10 bulbs are 40 Degrees angle

Im using 4w SMD LED Lamps but there too bright too look at so thinking it should be enough.

4W SMD LEDs normally have a 120 degree angle. however they are not as bright as 35W halogens and the spread of light reduces the specific brightness at one point.

However with six 120 down lights the spread means that you get a significant overlap and should be OK.

my rule of thumb is to allow no more than 3'6" between LED downlights., and same spacing from the walls. that's using kosnic 5watt. so for a 18 x 11 room i would be looking at at leasy 12 fittings.

Thank you for that, I have just spent half an hour planning out the layout and I get that the light at usable level for a 40 degree lamp describes a circle 3.62' in diameter! Experience does better than design!
