True, because the market importing "budget" LED lights because people reluctant to pay money to try the good quality ones,
for example YEXX brand and EVAXXX brand selling RM80 for 16watt 6" light , my brand - Aztech selling RM128, Philip about RM140
there are quality LED lights, but not a lot of people will pay for it other than commercial client

Well a 25W PLCE CFL is about RM17 retail with brand, is about 1100 lumen, i don't think is lux - 44 lumen / watt
6W LED branded, RM39 bulb give you about 550 lumen - 91 lumen/watt

that calculation shows very efficient in energy saving, and normal house hold common area is about 200 lux design, which is very easy to achieve using LED, i will say energy saving is over design and waste energy. plus LED have no IR and UV ... CFL have mercury in it

PLCE lifespand 7000 hours, LED 35,000 hours
well that alone justify the money right, it last 5 times longer with 1 - 2 year warranty ?

PLCE no warranty

depends on size and type of LED and brand, good quality ones

4" about 90 +
6" about 130 +
spot MR16 , 90 +

but why you need 1000 lumen in residential area, usually commercial design will ask that kind of lumen
normal 600 - 800 is very good because house have low ceiling in malaysia

well, lets get a bit technical,

what is your living room size, color of wall, flooring color, any mirror of reflective material on wall, windows area
i think your case if normal reading and studying , about 350 lux should be very sufficient.

ignore the lumen, because if you have a high lumen bulb, with bad reflector, you get low lux
always as design for lux , not lumen
