Question about Light Potency during seedling stage

Hi, i started this seedling about 2 and a half weeks ago, i started only using 130watts of light, to go easy on the seedlings, and to let it stablish, and develop its roots first, before i start giving it more light. So what do you guys think, have i given it enough time to switch to something stronger such as a 200watt MH, or should i wait a lil longer and let it grow a little more? Any suggestions are appreciated, thanks in advance.

Your seedling will be able to handle light as bright as the Sun. as soon as It pops out the ground.
There's no need to slowly increase light in seedlings.

Just keep the light about 3ft or slightly more above the plant top at all times if using a 600 or 1000 watt HPS or MH. CFLs are kept just inches above plant tops. Only newly rooting clones require low levels of (cool white shop light flours or low Kelvin CFLs with higher blue spectrum) light to match a slower metabolism till they grow roots.

It's not real efficient though..

If it were me at this stage, because I like to save money, bulbs, resources, not battle heat, and simply because it is a very healing spectrum for sick plants and seedlings, 1 CFL (6500k) for another week, then maybe two of them for at LEAST a week after that will be plenty of light and resources for such a tiny sprout.

That's just me, everyone else's own mileage may vary.. I always get a kick out of seeing a tiny seedling under the whole easy bake oven production, but I don't do it myself.
