Modified MTE SSC P7 900-Lumen 2-Mode

[hanachan]

Hi, I'd like to show you my fourth modification of the flash lights.
The light is MTE SSC P7 900-Lumen 2-Mode from Dx.

My first mod is
Romisen RC-G2 Cree Flashlight: not so bright, not control the switch.
the second is
UltraFire C2 Cree MC-E Flashlight: recently lighting is suddenly very weak.
the 3rd is
Romisen RC-T6 (reported at this forum): good but somewhat big.

The picture shows the finished form.

My modification has progressed. The size is almost the same as before mod.

Main mod. is replacement of the tail push switch with the mini toggle one.

This light is compact ( 16cm long ) & bright! So it may be one of my favorite U/W flashlights. I'm not sure how long it works well, though.

Its detail is here.

Any comment is appreciated.
Thank you.

How did you waterproof the light ? With the front lense and the middle part where you change the battery... ? Have you dove on it yet and if so How deep have you taken it to...? Looks good and under 35 dollars its pretty cheap for a bright dive light

Have you dove on it yet ....t

A Dove is a bird. It is not a term related to diving at all.

unless the dove dived down

So have you dived with it yet?

Thank you for attention.
The waterproof method is the same as previously reported. please see this page (in English & Japanese).

glue one more glass lens from inside and the round acrylic plate from outside of the flashlight lens.

About the battery change part, usually at this part there are single or double O rings. But I don't rely on the O ring's function. So I paint the sealant on the thread (not remove the O ring) and after a while I screw the tail cap. After then I bind up the conection part with seal tape and in addtion bind up the part (over the seal tape) with vinyl tape.
In brief the battery change part is glued up weakly with silicon sealant.

Yes I have dived twice with this light: max 23m depth 40min & 10m depth 50min. No water invasion. When I tested the modified Romisen RC-T6 reported at this forum, this light was in my BC pocket. As described at my HP page then I could not switch off the light. So I dived with the light without battery.
Now I have remade the switch. Since remaking the switch I have not dived yet.

I wish my English understood. Thank you again.

Interestingly enough if you go to Dictionary.com it shows that dove is a past tense of dive. Upon reading further it explains where it came from and its usage.

Usage note:
Both dived and dove are standard as the past tense of dive. Dived, historically the older form, is somewhat more common in edited writing, but dove occurs there so frequently that it also must be considered standard: The rescuer dove into 20 feet of icy water. Dove is an Americanism that probably developed by analogy with alternations like drive, drove and ride, rode. It is the more common form in speech in the northern United States and in Canada, and its use seems to be spreading. The past participle of dive is always dived.

Apparently only we stupid Americans and Canadians use it as a past tense verb. In conclusion you both were correct in you usage.

 

[hanachan]

Ah.... 'dove' is used in Americans & Canadians but the pp is always 'dived'.
So both are incorrect. OK?

Thank you for the info.. Yes packhorse we in US speak differently and use our words in many ways... That light is off the Hizzle, its got me all Crunk.. I sure would like to have one in my Crib.. Urban dictionary.com great Job on the P7 light.. Its a great LED and packs a punch

Has this light now been to a decent depth (cos i think it will leak!!) and do you have any under water beam shots?

 

[hanachan]

hi, thank you for attention.
I think no dive light without leak...

I have dived 3 times together with this light at max 20, 23, 27m depth resulting in no leak.
The beamshots of this light are shown here (my HP).
One of them is at the thread titled DIY water-cooled & sectional P7 UW light.
'B' shows the beamshot of this light.

So I paint the sealant on the thread (not remove the O ring) and after a while I screw the tail cap. After then I bind up the connection part with seal tape and in addition bind up the part (over the seal tape) with vinyl tape.
In brief the battery change part is glued up weakly with silicon sealant.

Hi, I don't quite get how you waterproof the battery change part, i,e the head and the tail cap unscrewing.

* Have you blocked off both sides?
* Do you re-glue after each battery change then?


Myself, I got one of these similar lights, but i managed to break of the battery tube while trying to unscrew the head. Apparently it was stuck, maybe thread lock?


Cheers

Sorry for late response.
I will try to explain how to seal the battery exchange part (screw) again in my poor english.:candle:

temporarily the parts ( screw part) are named as follows:

The frontal, body parts (screw or thread) are permanently ( of course really it's not permanent) glued while the battery exchange part is weakly glued.

I will show the sealing process with the photos concretely:

You can see the broken silicone sealant at the battery exchange part (white part).

unscrewed and opened it.

The silicone sealant is localized at the O ring portion.

Now I will seal there again.

prepare the seal tape (white one) and the silicone sealant named 'bathbond' which is used for home bathtub sealing.

small amount of the silicone sealant on the mini screw driver.

paint it around the O ring.

screw up the tail cap.

The sealant is sticking out of the junction.

flatten the sealant.

twist the seal tape on the sealant.

The waterproof method is accomplished.

twist a vinyl tape to protect the sealing.

accomlished!

make sure the lightning.

usually I do this method the day before diving.

Opening this part is very easy. remove the vinyl tape, the seal tape and
unscrew the tail cap. The sealing is easily broken. This is shown at the first photo.

Sorry for many photos.
I hope this description helps you.
