The angle of the lights should not matter but the intensity of the light will diminish inversely proportional to square of the distance from the light source. Which means that if you have a light bulb 4’ from your work surface and you move it to 8’ feet away you will only have 1/4 of the light reaching the work surface than before you moved it. To compensate you have to add more lights or increase the bulb wattage. So the extra distance of having the lights in the ceiling may cause you to add more lights to get the same amount of light to your work area as the hanging lights would. Only you can decide if the trade off in the cost of the lights and additional electricity is worth it. Look up “inverse square law” to see the science behind my point here.
