Received my relative cheap Ebay "4000 lm", "120m" Dive Light in the mail today and wanted to share a little with you guys.
Light uses 2x18650 LiIon batteries. The ones that they supplied to me made the light extremely weak. Changing over to the ones I already had produced a much more decent beam. Size is very manageable and overall build seemed pretty solid with the O-rings well lubed and threads smooth. Had a very solid feel to it.
Easily unscrews into 3 parts, Tail end is flat, so might be easy to drill a hole and attach a gland to it for modification into a canister light, which is what I bought it for.
Light head is of a good size, and looks like it would fit a goodman handle well. Seems pretty ideal as a light head in a canister light. Unfortunately, threads for the tail end do not fit into the head. =( Otherwise it would have been perfect.
Beam shot: Beam is quite strong but looks like there is quite a bit of spill. Reckon it would do better with better optics which is what I am hoping to do. Attached below is the beam from my first dive light, a UK C4 eLED rated at 275 lm.
Beam is clearly much more focused in the C4 eLED. But, the Ebay light is definitely much brighter. Superimposed, you will be unable to detect the C4 eLED beam. However, calculations and practicality aside, there is no way this light is close to 4000 lm. I would be surprised if it's actually any more than 2000.
So questions for this light are:
1. Does anyone have any suggestions as to how I may be able to break into the light head and access the electronics to modify it?
2. Any ideas on how I can seal the tail end to the light head given the threads are of a different size. Threads for the tail end larger and so it fits it but does not screw at all.
Any thoughts are much appreciated! =)
