lighting needs

I'm doing up a room in my basement that is 13 by 17 (221 square feet.) I have 6 recessed lights, each has a 50watt bulb. Will I have enough lighting if I just install 4 of the lights (200watts) for a room that size?

 

how many lux you want, how far below the ceiling?

Floodlights or spots?

resi. living room 50 lux
resi. toilets, hallways, 80 to 100
School classrooms, Kitchen work areas, office lighting 300 to 500
Garment manufacture - sewing, Supermarket 750
Instrument assembly 1500

A 50w halogen flood might give you 1100 lux in a 4' dia. circle 5' below the ceiling.

To check your existing light levels you need a camera
With ISO 100 speed film, an Exposure Value (EV) of 6 equals 160 lux, 7 = 320, 8 = 640.

 

Yes for code compliance, no if you like lots of light. Go LED

 

LED's are still expen$ive
I keep looking but at $20-30 a bulb I'll stick with free CFL's (after instant coupon)

If unfinished area (open ceiling)
I connected a couple recessed cans with power cords & then plugged them in to see how the area would look
I used 6" cans so that I can use any bulb I want
If you are going with the MR16 fixtures I would not do it
