if I replace 4ft Conventional Tub light (6500k Lumens) with 10w LED Bulb (6500K Lumens), will the LED BULB light cover same area as covered by Conventional 4ft Tube Light?

No. Tube light has much better coverage even at the same wattage. In your case, you reduced the wattage by at least half assuming that you replaced a 40 W fluorescent tube light with 10 W LED.

6500K is the colour temperature, what they call cool white. 2700K is the other end, warm (yellow) white.

10W LED bulb would be around 1,000 lumens.
4 ft conventional fluorescent tube is around ~2,000 lumens.

That said, even if you do get a matching 20W / 2,000 lumen LED bulb, in my experience a longer 4 ft LED tube is better at spreading light.

Dont replace it with bulb, replace it with equivalent lumens led batten with good quality LED which cause less stress on eye.
 
Any LED visible to our eyes is stressful and photo-biologically harmful.
Best is ceiling surface cob lighting with low ugr.
If wall point is only option, then you should put Track lighting pointing towards ceiling, calculation of lumens being 0.6 x square feet x 100.
Average is putting a tube light on ceiling with 4000k, and lumens should be 0.6 x square feet x 100.
Worst is led tube light on wall (Normal tube rods were way more soothing than led tube lights on wall, so when technology changed, placement also needs to change)
Killer is led bulb on wall
