I fitted an 45W LED batten to replace 2 standard fluorescent fittings (1 x 6ft & 1 x 5ft), fitted the opposite direction, so it went along the length of the garage rather than across. I think the single LED gives more light than the 2 did. and it's a better quality light. I do work for a company who sells them so knew a fair bit about them. Look at the lumens and the light colour if you can find the info. The colour or temperature is it's sometimes shown as, will be a K number, the higher the brighter. For example 3000K is more of a yellow light, whilst 6000K is classed as daylight and gives off a much whiter light, better for working in a garage. The higher the lumens, the brighter the light will be. Happy to help if you need any more info.
