Ordered 12/15/11, shipping notice 12/21/11, received 1/11/12mine was just shipped today and they said can be 14-20 business days to recieve. That means soonest im lookin at is the 30th of this month.
I haven't had time to do much with the 1.2W waterproof 445nm. It came in on-spec (per the power certificate) and I've got it soaking in saltwater to remove any oils left over from manufacture and to make sure it's absolutely waterproof before submerging it in my tank.any updates on performance?
Wash and dry prior to returning to their locked caseThat sounds promising for those things that you can get close to. Be sure to rinse it off with RO/DI water so that you don't get any spots on the lens!

None - the firm I ordered from has "lost" 2 orders and hasn't responded to my latest email inquiries. I don't think they have it in stock. I'm going to have to find another source.Have you had any luck with the OD4 acrylic you ordered?

I had a few moments this morning to test the underwater 1.2W. Initially my prior problems reappeared, being unable to obtain a fine enough focus point to achieve burning - then it dawned on me. Air was trapped in the hood containing the lenses. Once I inverted the laser underwater allowing the air to escape, it functioned just fine. I observed the following,
So far, it looks like the underwater option is viable and likely a safer option as potential reflections are minimized. Because you're able to work much closer to the target, you're able to use your hand to at least partially sheild the beam endpoint from the tank's inhabitants.
- Although the lower power output is noticeable, I think it is mostly offset by being able to place the laser much closer to the target and by avoiding any power loss due to reflections off the tank walls.
- The cooling power of the water if significant. This laser has a 60 second duty cycle. When used outside the tank, the laser would be very warm to the touch after a minute of lasing. When used submerged, the duty cycle seemingly becomes irrelevant (at least as far as thermal management - there may be some advantage in allowing the batteries to recover) as I detected no temperature increase despite many minutes of continual lasing.
- When used underwater, it seems the battery capacity will become the new duty cycle. As this host uses smaller 16340 cells, I noticed a significant power drop off after ~5 minutes of use.
My "focus" has been on Xenia as all else has been relatively simple to eradicate. Xenia is proving to be the greatest challenge. It typically takes multiple sessions over the course of a few days to completley kill it. You basically have to lase it until it's little more than a "blob" to prevent it from regrowing.Did you try it on xenia and gsp? I like the ability to put the laser closer to the target. Seems much safer.
I have not targeted Zs or Ps, but I see no reason why it would not be effective. The general rules seems to be that lighter colored - larger mass items will take longer to eradicate. Any coral or pest I can imagine could be destroyed by a laser. It's simply a matter of how much lase time would be required.Has anyone tried eradicating nuisance palys or zoas?
Congrats! I'm sure you also ordered eye protection right?Just ordered a 1.2w 445nm with an underwater host. Tremble in fear, aiptasia... :xd:
yessir!Congrats! I'm sure you also ordered eye protection right?
