I use the same. The advantage of the button is that it lets you have a low power mode. The high setting on this is too bright at night for most uses in clear water. It is handy for looking in holes and under ledges during the day.Everyone in my family uses this light from DGX. It has high, low, and strobe setting. The low setting is almost always enough for most night diving without being blinding

Note that there are many very similar versions of this light. When night diving, I also carry a second one I picked up from Amazon that's no longer available. There are versions on ebay you can get cheaper if you are willing to go without a warranty and you have your own charger. Mako offers a version and also sells accessories like a wrist mount, belt holster and speargun mounting bracket 1000 Lumen Dive Light
