I removed the lens and it looks like it is doing around ~20k lumens without the DC-fix. A bit lower then most but there is a 14% tolerance for these LED’s so still well within the tolerance range. I am going to try a few things to see if I can improve that number any, my cells are not fully charged either.
You have no idea how much relief, last night was not fun trying to figure out how I would come up with the money to replace several lights and buy new LED’s.
Yeah, I was shocked that someone would even think about taking a usps package which is why I was not real worried about those. If you take a usps package that is an instant felony, they don’t mess around with that. So I have never really worried about leaving them out, particularly in my neighborhood.
UPS and fedex fall under different rules though. I usually drop them off personally for this reason.
I am just glad it is behind me now.
Ok, got my second light of the day finished. This is the second one for BORO. He once again wanted some 3000k 80cri LED’s 50% ramp and bypasses.
This one is doing even better then the last one though, I am getting ~21k lumens on this one vs 19K on the other one. I checked both again and the numbers were consistent. Just the LED lottery I suppose. Still well within the +/- 14% tolerance Cree gives.
Still the nicest high output warm white light I have seen yet. Most WW lights are low output it seems.
Now who oh who is next…
For anyone they may have wondered about thermal protection well... it works and works consistently. That last video I shot where the local youth baseball and football park is was supposed to have been left open for me you can easily see the light step down. Let it cool off even just a minute or two and kick it right back to turbo.
I think I will give in and change the step down temperature in mine just a little hotter. Other than that the driver and UI seem flawless.
Excellent work TA.
By the way I will be needing at least 1 more 70.2 driver for myself. I will be keeping one of if the 2 colors. I think probably the blue. Q
Ok, here is #3 for today, you know I should consider laser engraving these lights, if anyone is interested let me know. I do have assess to a laser engraver and could engrave whatever you want if you send me the design on the light for a fee. I would have to figure out the fee if people are interested but most likely around $10-$15.
This like is SVK89’s second light, this one is a black XHP35 hi light and he wanted a mixed tint setup with 2x 4000k 80cri and 1x 4500k 80cri. Not a bad choice at all, a very good final tint and around 5800 lumens.
This time I know who is next, it is Newlumens xhp35 light, I kinda got these lights mixed up at first so they were both disassembled on my desk for modding.
And #4 for today is now done, Newlumens tan XHP35.
He wanted XHP35 HI 5700k emitters, TA driver and 100% ramp.
These are actually pretty good for a CW emitter, They are on the cool side for sure but even I could stand them if I had to. Much much nicer then the stock CW and a lot brighter as well.
This is the highest XHP35 light yet (which makes sense, they are the highest bin yet as well unless someone trys the E4 bin I can get from another supplier for a short time).
It is making ~7200 lumens on my sphere. Quite nice indeed and further confirms my suspensions that the stock CW are something like C2 bin or a little lower.
Do you have any of those left.. if so when I start shipping this new batch to you I will send mine along too.
Oh no, that’s the lowest for all the 4000k you’ve done so far. Hopefully it’s the batteries. On the stock lights, fully charged batteries and non fully charged makes a big difference in output.
None left here but I will be making another order anyways, I can add them to that if you want them, we can discuss it later.
Yeah, I was wanted to know that as well, I pulled it apart and resoldered everything but didn’t change anything. I will swap out the FET and see if that changes anything in a little bit, that is the only other thing it can be besides the LED’s themselves that I can think of.
That said This is not uncommon when building big lights, some just make more or less then others for no apparent reason. This is why I don’t guarantee any number, just like CPU’s and the silicon lottery, some LED’s are simply better then others, for many of the same reasons.
And it looks like the final light for today is done, Newlumens Blue XHP70.2. He wanted the P2 5700k in this light with 100% ramp and like his xhp35 the tint is very better then the stock CW, almost acceptable to my NW picky eyes. If I had to have a CW light, these would be the ones I would get. I can not stand the stock LED’s.
Final lumens show it doing ~22k lumens, not bad at all.
Being able to try all these different combos and seeing all these colors in person is neat. I really like these colors.
Ok, swapped the FET, checked everything over, put it all back together and tried it again with cells fresh off the charger and it is now doing about 23k peak stabilizing around 22k. So that is more like it.
You a wizard!
I wonder if those E4 min would make that last 300 lumen lol...
Hey there,
I came across Terry’s site & want to order the Haikelite MTO7S XHP70.2. What is the process to send it to you to mod it to this 20K lumen monster?
Chris
On paper it would, it should be about ~21% brighter then the D2 5700k HI LED’s he used. Although many times paper numbers and real world numbers don’t line up perfectly.
Simply order the light from Terry like you normally would but tell him you want to ship it to me and give him your BLF user name to send with the light.
Then contact me via PM to work out exactly what you want done to the light. Terry will send the light to me and I will mod it and then send it to you.
TA, How is the tint like for shave dome P2 5700k XHP70.2? any green tint? Color temperature around 5k? Tint shift better or worse?
20K+ lumen is for the MT09R 70. The MT07S is single emitter and does, what something like ~9000 lumens or so with TA driver?
Thank you sir… xhp70.2 is cranking 22,000 lumen and xhp35 7200 lumen. I couldnt be happier. Mt07s will be on your way soon.
