i just picked up a duracell 140 lumen from biglots for 10 bucks. it was the last they had or i would have bought them all...lol
i have been using an led pen light that works fine for checking veins and movement. this 140 lumen will have to wait till next year. more than 150-200 lumen i think could be hurtful if the eyes are developing though. i dont know this for a fact but its a good assumption.
