I needed in short notice a divelight as my primary broke and budget was limited at that time / not sure which direction I will go.
I went with a DL30. Well its ok, used up to about 35m depth in fresh and cold water. Burntime and notification (short flash) for battery almost empty for that power setting is ok.
The switch is not my favourite for gloves. Also brightest setting will trigger a pcb protection from the battery, at least for 18650. The lamp came with an unprotected 21700, I have no protected 21700 to test with.
I do not like the spot. Its has a too large opening angle, and the corona is too bright. Burn time could be a bit better if taken into account the actual Lux values delivered.
