BTU lens swap - good results

Im worried with all of us going to olight with all sorts of made up stories of how we lost our sr90 lens and need a replacement will freak out the staff at olight lolzzz!! And i looked all over ebay / googled lots and cnt find any seller with a sr90 lens .

I emailed Olightusa first. Got a response the next day saying yeah they had one and for me to call them to order it the next day. Oddly the guy on the email told me it would $29. I had a family member call them the next day to order it. They told her no problem, but it was only $10. So she ordered it. It took about 3 days to show up. It was well packed. In a sealed sleeve, rapped in foam, in box stuffed with foam pcs.
There are several Olight sources out there. Olightworld, Olightusa, Olight-USA, etc. So maybe it won’t be to bad getting some.

:bigsmile:

i have emailed them and awaiting their response eagerly . With my upgrade to u3 and this lens upgrade ,i think my btu is pumping out the most lumens right now muahahah .looosers

(im still never buying anything from Ric ,I was a very good customer for him and least he could have given was a AR coated lens)

lolzz .Ryan hows the situation there buddy .i hear there's a war about to start? pray that everything works out and there's peace in the Korean peninsular

Not the first time this has happened, so we’re all good. :cowboy_hat_face:

Thankfully I do have a US citizenship, so I’ll run to the US embassy if it does break out. :smiley:

Rayan please dont run to the us embassy .im sure thats the first place theyl bomb ??duhhh !!!

iv been following the Korean war since watching "Mash " as a kid . what im amused about is how near Seoul is to the border! all the 12000 north Korean artillery pointing at 30 million people!!!

iv seen pictures of north Korean soldiers and they look starved . they can see the prettier fully developed southern ladies/i phones/cakes/tons of electronics /LED LIGHTS LOLZZ across the border! Now they l be like zombies trying to get all these once a war does start! iv been thinking of this for a long time! phew finally got it off my chest .feels good . anyhow wish you luck bro. I am familiar with UN peacekeeping duties around the world and so have seen my share of destruction.its sad

(Do you think kim jon will be shocked if i send a BTU shocker to him?

How easy was it to replace the lens on the BTU? Also, if it’s not too much of a hassle, since the lenses are too short, can you give us the exact diameter and thickness of the lens you recommend? I’m thinking about ordering a custom AR acrylic lens.

Thanks!

EDIT: I got the lens measurements form_the_’s exhaustive review:

Lens diameter: 94mm

Lens thickness: 3mm

How much wider would you suggest the lens be (96mm)? I assume the thickness is correct.

I heard they have an underground bunker… I may be wrong, though. :slight_smile:

Just to clarify which lens I’m custom ordering, it’s the UCLp AR Acrylic Lens from flashlightlens.com - assuming the price isn’t prohibitive.

I’d say 96mm would be a good size. The acrylic lens I don’t have any experience with, so I don’t know how well it will compare or hold up to my glass UCL lens. But if the will get you one for a reasonable price, its would be a reasonable choice to try.

So you are no longer buying anything from him because he didn't give you something not in the description of the item for sale?

I personally have no issue buying from Ric again. The BTU is a beast of a light with its only comparable rival being the TK75 when power, throw, price, quality, and flood are all considered.
And truthfully, the BTU comes closer to matching its advertised specs than 90% of the Chinese seller lights on the market.
That’s the way I look at it.
But Shaquille’s money, is his money, so if he’s not satisfied with the sale Ric made to him, I guess that his choice. I can understand that.
But I personally think I bought an awesome light for money from Ric.

You are, of course, 100% correct

I was simply confused by his statement above, which was at odds with his (relatively) glowing review of the purchased light.

If Shaquille is referring to the missing AR coated lens, he is correct. The product page does state AR lens, but it does not come with one.
Other than that, the product page matches the product better than almost every other light available from China.

Thanks for the info; I stand corrected and humbly apologize.

yes the AR lens + 800 meters throw + the sudden price drop . not sure if mine really had U2 emmiters in the first place ! cos now after upgrading to u3 the difference is so much that i suspect these were t6 emmiters. The only reason im satisfied now is due to my own upgrades.Once i add the sr 90 lens then itl be worth $180 .RIc has dozens of company available in china where he could have ordered nice ar coated lens in china for few bucks. why mislead us? .

I can be too picky at times i do admit but whenever you see smoke coming from my behind then someone started a fire there

will a tk70 lens fit in the btu ???

I’ll post here when I get a price. BTW, does the bezel just screw off easily when replacing the lens?

It’s super easy to change the lens on the BTU. The reflector is held on via the led heatsink/plate. So keeping the lens pointed down, simply unscrew the bezel, once off set the light to the side tailcap up to keep dust out of the reflector. Remove the old lens out of the bezel. Carefully set the new lens in place in the bezel. Set the light on the bezel, pick the assembly up and slowly screw the bezel back in place until snug. Done.

Thanks!
