I’ve been meaning to ask… can someone who has both a CW XHP35HI and a NW XHP35HI describe, or post a photo of, the colour difference between the two? As I showed in my post #1251, the “NW” that I received looks very much like a CW (cooler than a CW Acebeam light I have), so I’m wondering if the CW XHP35HI looks about the same, or if it’s even cooler than my very cool NW.
One calculation I forgot. I just measured it 3 times at 5 meters using 2 different meters and it's right.
Keep in mind this is using TA's version 1 driver in a 35 high MT09R
Total lumen output for the version 1 driver I have been playing around with is 6500... It will be extremely hard to get very much more without overdriving the LED's.
The overall output for a thrower is not nearly as important as what is actually designed to do which is throw.
So far it's easily 1000 meter thrower.
That video I really wished I had put a camera much closer to the target so it would show a little better just how well at 822 yards it can easily light it up.
If time and local law enforcement will cooperate I may do that shot again. But if you can see it on camera that is at the same distance as the light you can bank on having made the grade.
At 5 meters I got a reading of 11300 lux... if you understand how to do the math double check. Lol I did 3 times with 2 meters.
I was sent one of both for testing, I have not tried them side by side yet but one after the other there is a noticeable difference but the NW is on the cooler side of Neutral I would say for sure.
There is a variance in the tint of LED’s in general and seeing as these are pretty low bin, I am guessing that the binning is also not very tight. So this is not very surprising.
I'm not sure if you remember me telling you when I first called you.. for some odd reason all the NW 70.2 versions were measuring higher than the CW... it is usually the other way around. Not really enough to matter but somehow all the NW models did measure higher.
Like I explained earlier with low bin emitters like they are using in these lights, there is every possibility that the NW is simply a higher bin or has a lower Vf. So It is not that surprising really.
Plus with the latest gen emitters they are releasing the top bins in the warmer tints now. So the days of CW always being brighter are numbered.
Terry, I don’t think this tit for tat does anything for the GB and your business. I’ve been following both your GBs and I think that there are positive things you tried to do but there are a lot of things that just didn’t help the situation at all. I think a lot of members/buyers took a chance on this GB, even though Haikelite has less than a stellar reputation around here because YOU vouched for them and said that things were going to be different. Due to your positive energy about the lights and the company, people decided to take a risk and join the GB. Now let’s get this straight you did this GB not only out of your graciousness to provide us with a discount but it was also to promote the brand and your new business. So it doesn’t sit well with some of us when you imply that you were only trying to bring forum members a benefit with discounted price on lights and you were only trying your best to help everyone out here.
Now we only “risked” our $105-$125 to buy the lights but that is a decent amount of faith for our budget light community. Especially considering Haikelite’s track record around here. Of course this is nothing when compared to the amount of money you have lost on this GB, but then again this is a business venture for you, unlike us. I think we all sympathize with you for being in an unfortunate situation but that is also the cost of starting a new business. I think many of us here that have had their own business or own their own business can sympathize with you even more.
Now Haikelite, the manufacturer, may have made a lot of false promises to you and us. However, where you fell short here was not being upfront with us and continuing to spin everything in a positive way even though the situation was less than positive. I’m not going to list what the shortcomings are since I think everyone here knows what I’m talking about. It really doesn’t help when we are just looking for answers, when you make comments like, well even though it’s not up to the promised specs, it’s still a good light and a good bargain.
Still I think you did great by trying to pull through and rectify the situation as best as possible and we appreciate your efforts and the discounted price. If are more straightforward with your statements and keep the puffery to a low, I think that people will continue to buy lights from you.
We are preparing the shipment for all charging unit during group buy. As the packing for charging unit has not got ready, we will use normal packing to ensure the safe arrival this time.
For those who has issue with original 09R driver, we will send a replacement driver later which designed by TA later.
Winston Wulf,
At the risk of being added as the third troublemaker in Terry’s list, I would like to say I have not found your posts to be unnecessarily negative, mean spirited, or provocative. Rather, they have frequently been quite relevant, informative, and as far as I’m concerned your contribution(s) are welcome here.
I’ve been active on usenet since the early 90’s (arguably the “primal” model of contemporary forumming), and I would venture that there are not many hard rules to forum posting in general. But, I think most of us might agree that if the central theme of a post is to diminish or besmirch someones character, that post is, at best, worthy of being ignored. A bit of dramatic flair when engaged in an otherwise reasonable debate seems to be well tolerated. But when, by use of cliched negative association and derogatory assertion, a post appears to have the singular intention of simply making someone feel unwelcome, I feel affronted, concerned that the power so commonly wielded by cults of personality and privilege will come to dominate this space, neuter the potential of what is perhaps the most significant development in human communication since the printing press.
Or perhaps I’m merely overly sensitive to bullying. Take your pick, it ain’t pretty…
Heikelite hired subcontractors to develop a driver.
Once the light hit production it turned out that some lights flicker.
Well, it happens. Fix it and move on. Fix the culprit by switching to a better subcontractor.
That’s OK way of handling the issue. Also send a fixed driver to the buyers. That’s a good way of handling the issue, despite the fact that quite a few buyers will be unable to solder the driver.
But the drivers were also missing some important features too (LVP, thermal control). And the presence or absence of that features were easy to verify. If they didn’t find the problem, they clearly didn’t do a regular test of what they put in their product and that’s bad. I hope they learn from this lesson as well.
I would also like to express my disappointment with them faking the specs again.
Now that I learned that they used very low bin LEDs (that should never happen in a brand light) I view MT09R as a very interesting host with some rubbish inside.
I was not a fan of Haikelite, but in MT09R I see 3 red flags:
careless development process
fake specs
very low bin LEDs
Sounds much like Astrolux to me. But for a premium price.
Okay with Critics and debates not withstanding I do still have MT09R's in both models and TA should be completing the final version of the drivers very soon and I have already requested enough drivers for the units I have left.
There is a slight difference in price but that is just to cover my cost of the drivers.
Orders can be placed anytime and they will ship the same day the drivers arrive and I install them.
Future models should have the same driver but that will be several weeks before I can even hope to order them myself.
