Is there a brighter bulb for this?

My friends dad just got this, Craftsman 009-11391 Craftsman C3 19.2 V Work Lights | Summit Racing. But it only puts out like 30 lumens, being it’s a krypton running at 19.2v and .6 amps. Is there any brighter bulb, or led drop in that he could get for it?

Here’s the bulb it uses http://www.ebay.com/itm/Craftsman-19-2-V-Krypton-KPR-Flash-Light-Bulb-6-amp-/330609087711?pt=US_Flashlights&hash=item4cf9d654df

If you are unfamiliar with how the bulb is situated, the end is connected to a contact point, and the side of the bulb is connected by a spring that wraps around it. Basically a 3/4 inch spring, with a contact point at the bottom of it. The bulb just sits in that.

I believe this lamp is an almost direct fit for those old standard incan bulbs:

I know some people at work have it and it seems to do fine.
