Zozz so lower lumens, but did you get more throw? Odd how that works, I get that it throws farther because it’s focused better, but why do the lumens go down?

With dome I had 226125 cd
Without dome I got 355500 cd

The lumen loss is because no reused light because of dome missing. With dome some of the light reflected back from the dome surface to the phosphor and then it going out again so it reused. I can’t explain it any better but I read it somewhere more better explained. That is why a Wavien is used in Aspheric high output mods. It reflects back that light which unused and othervise not hit the lens.

I do like the Lumintop BLF GT very much. I have this idea of line of succession of best flashlights. It goes, 6D Maglite, Surefire M6-CB, Olight SR90, Lumintop BLF-GT70.

Totally only my own view. Big Smile

Yes, you will loose some lumens but gain throw.

As a general rule we have been seeing around a ~40% increase in throw and a ~20% loss in lumens with the XHP70.2’s.

Based on my own testing I would say it generally gets around ~400-500k warmer after the dedome but the green tint shift on most LED’s is what stops me. We will have to see what people think of these particular led’s when it comes to that. So far I think someone said that the CW did not have much / any green after dedoming.

Ordered on 10/19, received today 11/1 – Chicago, IL.
Cells are charging; trying to suppress all the giggles.
Cheers all.

Editing to mention, Lumintop threw in a shoulder strap for me for free. Very delighted with this group buy. Thanks.

Thanks for the info Texas and Zozz!

That wavien looks nuts! I wonder what that would do for a GT70!?

Green doesn’t bother me so much I don’t think, this isn’t an often used light, it’s more of a wow factor light. But by that standard I’d want it as cool as possible for the light saber effect. We’ll see what we get!

I want to thank the wonderful leaders of BudgetLightForums for recommending the magnificent Lumintop BLF-GT70 to me. It is very affordable, super high quality, and very well thought out. My 2nd one just cleared Customs and will soon be delivered to me. Crown Thumbs Up

Mostly nothing. It can’t be used in reflector lights. Only in aspherics.

Dedoming does make a noticeable difference with this flashlight, the hotspot decreases in size a bit but I can tell that it does throw farther. There is some tint shift when dedoming the CW xhp70.2, but honestly unless I’m blasting the bushes 50ft from me I can’t see any green and it really does improve the details that you can see at distance. I do notice that there is slightly less of a “barrel” of light coming out with the dedome but since I already own a very high output thrower(X65vn 5000k)I wanted something a little different so losing a few lumens for throw was worth it. Overall this is a really fun flashlight!

Thanks for the info! This is encouraging. As far as less of a barrel of light, you mean less flood nearby? Or less wide beam, but it throws farther?

I wonder if that doesn’t help the apparent throw distance? Because less light spilling out in front of you would make the light reflecting back from a mile away seem brighter by comparison?

LOL, it might be time to invest in a 4 cell charger.

The spill light is light directly from the led missing the reflector. So if slicing the dome looses 1000 lumen, then the spill will be 1000 lumen less.

I’m sure he means the hotspot beam angle is narrower. This increases throw distance. The spill angle stays the same.

JasonWW hit the nail on the head, the circular mass of light coming out of the reflector seems to be a smaller diameter but it is very intense along with a good amount of usable spill. Very happy with the dedome but truthfully I was very happy with the dome as well.

Very impressive, they look like ready made marketing shots. Thumbs Up

I added them to the OP if that is ok.

Why didn’t the new switch fit through the switch hole? Was it thicker?

I could not get the switch to go though the hole from the inside, so I fitted it from the outside.

I found the switch wires too short to install the switch from the inside.

Was I missing something?

I am happy to report that my Lumintop BLF GT70 beam profile feels even brighter and tighter in hand. This is the best flashlight since the Olight SR90! Big Smile

I assumed people would not have to solder the switch wires.

Did your GT have the two slots (shown in picture below above & below the switch)??

If so, you should have been able to turn the switch sideways & insert it from the inside without unsoldering the wires.
