Burns through batteries

Every wk felt like I needed to replace..

From the lab: PTEC - BYTE Headlamp

Posted on

The BYTE headlamp puts out 50 lumens in a spot beam with its two-mode Maxbright LED. A red Ultrabright LED helps you keep a low profile and preserves your night adjusted vision. BYTE is stable with its asymmetrical single arm bracket and the power button is easy to find even while wearing gloves. BYTE runs for up to 146 hours in white mode on just two AAA alkaline batteries. This headlamp is also lithium battery compatible.

Chill mode

I experienced the flickering last weekend in 23 degree wind. I doubt it was an overheating issue. My take on it was cold batts (alkaline do well in cold for me) After a rest, by flipping the top Batt I was able to leave it in red mode the rest of the evening after which I cycled the switch and experienced the same dim flicker that would not turn off. All that being said, when it works you can't beat the light for the weight. I hiked out at night in red mode. if the bug gets worked out i feel it is a superior product.

Sounds like you have an older BYTE, and the alkaline batteries are highlighting the circuitry issue. You should be able to exchange it for a Byte with updated circuitry through your retailer, or call up PTec warranty line for help directly from us: 1-800-257-9080 http://www.princetontec.com/index.php?q=contact_form/contact_us

good choice

I seek simple Headlamp for use one day hiking,
Princeton Tec Byte Headlamp is good price, and
enough to blight.

Nice super lightweight headlamp.

I currently have three of these that are shared between my wife, my brother, and myself. They are very small and provide all the illumination that we needed last weekend during a couple nights on the AT. The settings are perfectly adequate with a low red, a low white, and a high white. The lights come on in that order with sequential pushing of the switch. It's a nice feature so you don't blind yourself with the white light before switching over to the red for night vision. When activating my previous headlamp it would switch on the bright white LED first, thus blinding you and trashing your night vision before you were able to switch over to the dim red LED.

So far these are perfect. No issues or problems. They have been perfectly reliable. I haven't seen them in a heavy downpour but the light rain followed by freezing temperatures we had didn't affect them. They are listed as water resistant so I imagine they are at least splash proof and appropriate for rainy weather. The batteries showed no signs of weakening and they appear to be plenty sturdy for average use.

Because of the light weight and small size I am replacing my Petzl Tactikka headlamp with the Byte. The Tactikka is unnecessarily bright and has less runtime despite needing one more battery. It is probably built stronger, but I am not a soldier behind enemy lines so it is overbuilt for my needs.

The bottom line here is that this is a cheap light (I paid $15 at a retail store on sale) that is reliable, super lightweight, and plenty bright for campsite use. I love it and hope that it proves to be reliable for years to come.

UNTRUSTWORTHY

I can second many comments posted here already. I don't typically write reviews for products but I don't typically get something SO poorly thought out.

Both my fiance and I bought the same headlamp and both had the same problem with flickering light after MINIMAL usage. We used ours for one two-night backpacking trip and, thank god, only discovered the problem after we tried to use them after we got home. Upon quick research, lots of other people have had the same problem.

I WOULD NOT TRUST THIS PRODUCT.

Hey John,

Sorry you experienced a flickering. When the Byte was first released we had a small amount of circuits that would flicker when the batteries were low. This problem was immediately identified and corrected so the current Byte functions flawlessly, and there is no reason why yours should not as well. Please contact us (609-298-9331 or info@princetontec.com) and we would be happy to get new Bytes out to you and your fiancé so you can enjoy all the features of the Byte.

This problem does seem to be fixed. My brother, my wife, and myself all have this light and used it on a trip over a couple of nights. These lights were used for runtimes probably more than a couple of hours at a time while we were working around the camp at night. We didn't have any issues at all.

This is a great light. It is plenty bright enough for around camp or even on a late night hike. I love the red light on in it. It is super useful in the tent.

***There is a issue with the design of this light***

It overheats and goes into a death mode, which is a very dim flickering light that cannot be shut off. You have to remove the batteries and let it cool for 20mins. It only takes about 10-40mins for it to overheat depending on ambient temp. I got stuck in the woods with no light. NOT GOOD

I just got back from a 4 day trip using my light with no problems. I had the light on average about 20-30 minutes at a time every night. A few weeks ago I was also with a group and a few other people had this light as well and had them on well over an hour plus and there were no issues. What kind of temperatures were you in?

Responded on

I have one of these with the same problem, and we're not alone. According to the reviewers at backpackergeartest.org it isn't a heat issue but occurs when the batteries are running low, due to the circuitry used in the switch, which also dramatically reduces the burn time in normal use ie switching modes/on/off as opposed to continuous use. 1-4hours - very poor. This correlates with my experience.
Good news - there is a new version in 2011 which might fix this - no tests/reviews that I've seen yet, but the rep in live chat said this is the 2011 version and they have fixed the problem.
Meanwhile, for old models the 'solution' is to put new/charged batteries in. Leaving them out for a while provides a temp fix for low but not quite dead batteries.
