Unfortunately just read that according to the product instructions, and some divers reported problems, that it should be turned on before entering into water to avoid leakage
This is NOT good! OK for a light you'll have on 100% of the time, but not for daytime use occasionally looking under ledges.
Are you sure it says to turn it on to avoid leakage?
Old training is to turn a light on before entering the water at night to (1) help you find it if you drop it, and because (2) old-style (not LED) lights would often fail when turned on, from the power surge.
If this light's switch can't be used underwater, don't buy that light.

Unfortunately yes, see step 2 below

Hi,

I'm not really a night diver, I do dives up to 35m during the day, what I find is that sometimes I miss a dive light to illuminate sea life within the rocks, and on wreck diving.

I may do some night dives, but it will always be very occasional.

I know that I don't need a very big light, but I'm not sure I can live with those so little that fit in the pocket (unless they are very powerful but they surely will be very expensive)

I'm really on a budget there (up to 60€), so I wonder what would you recommend? I've received a Cressi Lumia Ultra Led (which I can return), 17cm by 5 cm, 250g w/ battery, the luminance (around 260 lumens and 25000 lux), and the light colour seems perfect, however the light may be a little too big and with too much lux for what I need?
As the others have posted, use a dive light with at least 600 lumens. Choose one with a small diameter head, and tie it off on a small bolt snap. Silicone grease on the O-rings every now and then.
 
Many thanks for your detailed insight.


So if we see the Seac T5 torch, with 9º beam and 300 lm, what do you think about that for the daytime?
Don't waste your time on 300 lumens when for the same price you can get higher output.

sorry but i disagree. i use the dgx 600 lumen lights. they have a pretty tight beam. they are great for caverns or night dives etc. but are over kill for day use. you can certainly use them. i have. but it is over kill.

you do not need that bright of a light when looking in cracks of the reef for little critters. in fact i would say it is counter productive. i have a UK 300 lumen lamp and it is more than enough. sometimes i actually wish i had a 150 or 200 lumen lamp.

It might be overkill, but I like the idea of having lights that can be used in all environments. And in the end, I'm really talking price. Divers seem to buy so much redundant gear. I'm thinking they may have a shopping addiction.
