I have done this myself years back and built stealth set ups for others, what we ended up with was bonsai plants and bonsai yields, though nothing wrong with the quality.
If I were going to do it again I would use household LED bulbs, cut off the globes. Aim for like for like as far as wattage and you will get significantly more light to your plants.
The good thing about that is you can pick up one or two here or there at any dollar store or anywhere that has an offer on and slowly replace them without a big sting to your wallet.
