HaikeLite Preview for MINI Triple-XHP70 prototypes--Discussion thread

Total Watts on a full batteries charge will be around 88 watts so divide that by 3? 8.4 volts with two full cells but we will call it at 8 volts flat. So 8 times 11 is 88 watts

Cree states that a XHP70 needs 32 watts each to achieve 4k lumens each emitter in this light will be getting about 29.3 watts so fairly close to the target of 32 watts.

This set up should achieve around 11k lumen at the LEDs? With loses around 9500-1000k lumens?

the output and UI is sounding very very good. lets hope the host has good heatsinking properties to have it run on turbo more than 2 minutes….

You have to take the voltage over the LED into account and not over the cells. The light is obviously current controlled, one LED gets a current of about 3.7 A, at this current Cree states a forward voltage of 6.41 V which implies 23.7 Watts only.

yea true sorry my bad! What is highest voltage these can handle?

I’m driving my Convoy L6 (single XHP70) with up to 12 A, according to djozz’s tests this implies a forward voltage of about 7.6 V. The LED is still working …

Dear Haikelite,

I would kindly ask you if you can tell us when the shipping will finally start? I bought the light through Amazon.

Regards,
Tom

Nothing new here? Did anyone have contact to Haikelite? I don’t get any answer since a few days…

Haikelite has never responded to my pm’s. Remember when they first asked to be messaged regarding buying their lights? I messaged them that day. They started so well. I wonder what happened. I already took a risk ordering an unproven light, and this is pushing me towards cancelling my order. Now if Haikelight wants to alleviate my concerns regarding risk by refunding me and shipping my light as a review unit, knowing that they’ll get a short review without the plethora of glamour photos and videos that full blown reviews here get, I’d be very happy with that.

I contacted them by E-mail the whole time. That worked quite well. But a few days ago they stopped answering… I also think about canceling the order…

Very nice. I like the double hole for the camera strap.

Very nice in case this is going to turn out well…

As far as I know the light is delayed and could be further delayed they sent a sample away to get professionally tested in a light box. They do not want to release the light unless it has met the figures they stated of at least 9000 lumens. Plus they had to make sure the custom programming was okay. Turbo mode runs for 2.5 minutes without stepdown.

Sounds like they were/are rushing things. The light is not ready, but it’s already for sale on Amazon. Then they don’t reply to mails. So how well are these lights tested if a lot of last minute decisions are made? It would be nice if we got a reply from Haikelite.

Yea. I do not think that many changes where implemented they where all minor. Look at every group buy we have the lights are not finished but we still buy them it’s not a big deal to pre-order . Plus the other issue is Chinese time is 2 hours before mine here. So when he is on at this time it’s like 1 am in China. It’s 3am here but I fell asleep 5pm yesterday afternoon so I am up lol. Then he has to work all day it’s only the one rep doing all this!

I agree that the changes are minor. Nevertheless I do feel that these changes that are made should have occurred some months before release of the lights, and not recently as it is the case. It just doesn’t feel right to me… The lights are also available on Amazon for purchase, and are not sold as a pre-order… Like I said, it feels like they’re rushing things…

It’s not a good sign that the changes come that late. It would be more interesting when or if the light will get ready. It seems that quite a lot people already bought it or pre-ordered it until today.

I just want meaningful communication. Delays happen with new products. Look at Kickstarter campaigns. Delays are expected. Backers get pissed, leave in droves, and some file lawsuits when there’s a lack of communication. Then there’s Elon Musk. He’s notorious for making impossible deadlines, and inevitably blowing those deadlines, but he communicates well enough to have earned the backing of billions of dollars from investors and customers.

Interesting how you brought up Elon Musk. He does play a role in my love for flashlights. When I have decided to purchase a new light after seeing many reviews and videos of it, I select the light… go to cart… pay… Paypal… redirect to Paypal… you know what I’m talking about right?

But all this doesn’t help me and the others who already ordered and are waiting for the information. I think at least Haikelite should give new information what happens now.

There's only one contact person from HaikeLite, so probably got tied up or something. It is weird though they started taking orders...

I don't see or can't find them on amazon US, but looks like their website can take orders.

I do know they are very concerned about getting all the details right for the production release, so my think'n is the delays are good.
