L-B030 vs. Ultrafire 20mW

[Deleted member 13229]

I have some DX points to spend and I am now debating over the L-B030 and the Ultrafire 20mW. All I want is a cheap waterproof green laser, which one of these is the better choice? I am currently leaning towards the Ultrafire because more people have had it, but the L-B030 looks better IMO. Which one do you think I should get?

hmm I have the L-B030, here are some pictures.

Here is the dot of the romisen (left)

I'm not sure it's waterproof...
Although it does have o-rings

Not sure if you are interested in the driver. It DOES have a pot.

I tested it to see if it was water-tight. It is definitely water-RESISTANT but there was water coming in near the end of the laser.

All the romisen lasers are good, they are pretty reliable and they all use the same module too   and they have AR 532nm coated lenses

Thanks for the help guys, I am now leaning towards the L-B030. Now all I need is someone to come in here and tell me that it is truly waterproof. ;D

the GITD tail clicky is useful aswell, and if you get bored with your greeny it gives you more to do with your BR

There's no such thing, especially at DX. There are diving pointers, but they're not in the price ranges of your choices.

Unless you're on a night dive and red is OK

Choose Romisen. It is waterproof. Well, as far as my bath goes anyway.

I showered with my romisen once.  ;D

And I will add that it is very stable too. When it was delivered to me the thing must've been sitting in the sun and was almost HOT to touch. But to my surprise it still produced a powerful beam. That said, I've also powered it up fine from the fridge as well.

The Romisens also have great heat-sinking, I took apart my L-C030 today and the heat-sinking was really good, it was also really easy to get to the module, it just screwed apart in sections.
