Re: Zebralight H51 details/preorder!!!

Man I'm getting antsy.


I've been waiting for the H51F to be released for months now. My wife was going to buy it for my birthday last month but it hasn't been released, so every week she's like "Can I buy your birthday present yet?"

hard to believe there are no other lights you would want for your b-day.

ive been waiting for the H31F, and i think thatll arrive before the H51F. also waiting for a H51w.

Re: Zebralight H51 details/preorder!!!

My H51 ran for ~45mins at full output on the 100lm setting using a fresh Duracell alkaline. After 45min it started dimming until about the 1hr mark and at that point the brightness was basically the same as the 30 lumen, so I switched it to the 30 lumen setting and after ~1min on 30lms it began blinking so I set it down one more level to the 8lm setting.

Its has been running on the 8lm setting for 9hrs and still has not changed to one of the lower modes.

I know it's not a good runtime graph but thought I'd share as I figure this light out. So if I was going to use alkaline in the H51 as backup I would first not use it on turbo, it doesn't take long maybe 10-15mins before you lose 200lm.

So now I know I can get at least 45min on 100lm so I could just use it for 45min then swap the battery. If I want to conserve I would start only on the 30lm setting and use the 100lm at burst only when needed/if needed.

I guess it's kind of stupid even testing it with alkys, I bet most of us will only use them when we are charging our NiMh and usually even then we pop in another NiMh.

However, and I think this is why I find myself wanting to know how to best use alkaline. This year we had terrible flooding in Nashville and surrounding areas I found myself in my attic trying to stop leaks and on my roof. I was also at neighbors and family members who live near by trying to keep dry what we could. I found myself using the H501 with spare NiMh cells in my pocket, I guess I had maybe four or five of them and throughout the evening they were all spent so I went to alkalines.

I was not using very good light discipline when using the NiMh but things where happening fast all around me so I just never though about it. I should have started with my H60 and used my 18650 cells but when a part of my ceiling came crashing down it took me by surprise and I guess out of instinct I grabbed what was most familiar to me the H501.

Anyway sorry for the long post it was not my intention but I found more respect for alkaline as long as I use them smartly and that's what I'm trying to learn about the H51.

Re: Zebralight H51 details/preorder!!!

I just checked this for you and the H31 body is slightly wider, the tailcaps are the same diameter so i guess that's where they get the 23mm.

With the H51 in the H31 clip there is a bit of wiggle room but that does not mean you could not use it because it takes a bit of effort to get the rubber back over the tailcap so it's not going to just come off on you.

thanks jhc37013 for the measurement.
i hope zebralights would include the H31 clip in the H51 package since the H51 cost US$5.00 more. or include a clip designed specifically for H51.
either way would help convince many members to buy the H51.

I can understand that and I'm still not certain why they include a clip with the H31 and not the H51. Like I said earlier the H31 clip is not the best fit but you could make due with it. Has anyone contacted ZL and asked for a clip even if it's the H31 clip? I don't use my H31 clip but if I did and if I lose or break it surely ZL has a way for me to replace it, either buy a new one or send one for free. I'm not sure but maybe they could supply you with one, if no one has contacted ZL and asked by either email or phone I could send them a email, they are usually very prompt with CS questions asked through e-mail.

Re: Zebralight H51 details/preorder!!!

I did almost forget to mention for those who do like the low-low's that the .8lm mode does have to my eyes anyway noticeable PWM. I don't see it on the standard 2.5lm only on the sub level .8 lumen. For comparison I do not see any PWM on my SC60 or H31.

Do you own any Petzl Lamps like Tikka XP or Myo Xp? I would really like to see beam comparison pics with th h51...

Re: Zebralight H51 details/preorder!!!

Can I ask H51 owners for a favor? Can you put some clear scotch tape around the lens to test the kind of fake flood the H51 can provide? If it works reasonably well, I will buy a H51. Thanks.

Re: Zebralight H51 details/preorder!!!

any straight beamshots would also be appreciated.

david, why not wait for them to release the H51F instead of just using tape?

Thanks for the info. I like getting spare Alkalines when I'm too lazy to charge up the few eneloops I have. Any chance for a test on eneloops? the 100lm mode is what I'm really most interested in...

Re: Zebralight H51 details/preorder!!!

I think david doesnt want to be restricted to Flood but have the option of flood light by using the scotch-tape.

Exactly! You can't turn a flood light into a thrower, but you can give a thrower some fake flood. Don't get me wrong. I love my H501, and will get the H51F too. But I don't know how long we will have to wait for that light.

I don't have eneloop I have Duracell 2650mah and I planned to test the 100lm mode using a fresh one tonight. I will report back and let you know what I come up with.

Re: Zebralight H51 details/preorder!!!

With a Duracell 2650 fresh off the charger with measured 2.8ah from the the BC-900 Lacrosse I checked the runtime at 100lms. I also used my HDS set at 85 lumens which looks identical via ceiling bounce test to measure output.

The H51 went 2hrs 15min before dropping to the 30 lumen output and then stayed at 30 lumens for 45min before dropping to the next lower level. While running during the first 2hrs 15min it did not dim at all and only got ever so slightly warm, and I do mean slightly like a Quark during the first 3mins or less.

I have a Petzl Myo RXP and I'm wondering the same. How much better is this?

Re: Zebralight H51 details/preorder!!!

Hope to see photos etc soon. Sounds great so far.

I'm sorry I don't own any Petzl's but I do have a PT Apex 130lm I plan on taking them out and seeing how they match up. I'm particularly interested in comparing the 130lm from the Apex vs. the 100lm beam on the H51.

IIRC the Apex gets about 2hrs regulated on max and with four lithium primary's it's suppose to be around 4hrs, someone please correct me if I'm wrong. If I used four(one at a time obviously) lithium primary's in the H51 at 100lm I would at the very least double the runtime at well over 8rhs.I've only tested the NiMh and alkaline so far in the H51 so maybe it's time to test lithium primary so I can confirm my own post.

Re: Zebralight H51 details/preorder!!!

I'm not concerned with runtimes at all. You know it's going to be close to published claims.

But I'm with the crowd who won't be buying the H51 "as is".

I really like my H501W and was thinking of getting another.

But with the H51 out, I'm going to wait until the H51W finally arrives.

I would also like to see it come with not only a pocket clip, but with the neck lanyard like the H50W has.

My .02, and since I'm pretty sure that ZL company people read these forums, I'm just making sure that they know what it's going to take to sell another Zebralight. :thumbsup:

Re: Zebralight H51 details/preorder!!!

THIS JUST IN!

If you check the listing on the Zebra site for the H51, you'll see that they moved the shipping time back another week so that they can include a pocket clip.

Well, you can't say that they don't listen to their customers.

Re: Zebralight H51 details/preorder!!!

HELL YEAH :rock:

They truly listen!
Thank you, Zebralight

Re: Zebralight H51 details/preorder!!!

YES! YES! YES!

finally they listened and took my suggestion to include the H31 clip.

zebralight do read the CPF forum ! :twothumbs

i will be ordering one H51 soon.

thanks ZL.
