Product Description

The brightest headlamp in our professional series, the Apex has been a favorite of extreme outdoorsmen and cavers for years. Truly the pinnacle of waterproof LED headlamp design, the Apex combines the qualities of both the Eos and the Quad. With a single Regulated Maxbright LED partnered with Four Regulated Ultrabright LEDs, the Apex provides either a powerful spot beam or a bright flood and switching between the two is incredibly easy. The four Ultrabright LEDs come in red, green, or white in order to suit your personal preference. Proprietary heat sink technology allows the LEDs to burn brighter and longer. The Apex is compatible with alkaline, lithium and rechargeable batteries.

I expected more from Princeton Tec. I really liked the light from this headlamp; it was quite bright for the size, and had a very nice field. The Byte is lightweight and reversible too (can wear it upside-down) I like to support companies who still manufacture in the US, however it has several technical issues however (design flaws, rather):

-Draws 50mA when OFF. I bought two of these headlamps, but after constantly changing batteries, I suspected something was amiss, and finally checked if it was drawing current when OFF, and sure enough it was. As an engineer, I find this completely unacceptable and a very embarrassing mistake on their part.

-You have to cycle through the brightness levels when trying to turn it off. My Petzl headlamp only cycles through the brightness levels when you're turning it on. After its on for a few minutes, it will simply turn off when you push the button. The Byte always cycles through the levels anytime you push the button. This time-out feature may have been patented by Petzl, but I find it quite useful. The Byte is somewhat annoying in this respect.

Update: Princeton Tec says that the battery drain issue HAS BEEN FIXED and will send me a replacement; changing my rating to four stars for good customer service.

So when it works it's a fine device but every time I come to it the batteries are dead flat. Poor design that has residual load when off.

Buyer Beware that this model, the Byte is defective. It hasn't been recalled and is still being sold at sporting goods stores across the county. It drains batteries while not in use. It's a shame because it seemed like a great compact headlamp at first. I'm not sure why the Byte is still on the market and being sold to buyers who might depend on this lamp in critical situations. After contacting Princeton Tech, they offered no explanation as to why this headlamp hasn't been recalled. After further search, I noticed that other customers had the same issue with this model. And this headlamp is still being sold on the market. Imagine that! Shame on Princeton Tech and I will never buy their products again.

I like the Byte. You can't beat the price.
The two white levels are pretty much perfect.
I really like the red led. Its the perfect light level for getting up in the middle of the night when you don't want to have to confront full light but would like to see to get around.

The ONLY thing I DON'T LIKE is the fact that you must cycle through all three levels to turn the light off. That means you get up in the night and go to the kitchen for a drink of water wearing your nice subtle red led... very restful... then you get back to the room, just about to jump in bed and you try to turn the damned thing off and guess what? You must confront the two bright white lights! Bummer! Double bummer if, in your near-sleep daze, you forget this critical info and do it AGAIN!

Other than that. I like it ;)

The packaging says this headlamp will provide 80 hours of light on high setting... NOT EVEN CLOSE! After about 5 minutes the light housing becomes very warm and after 20 minutes is extremely warm. I guess this is where all the power is going - HEAT not LIGHT. After 1.5 hours it was very dim on high and at 2 hours was just a faint glow - even the heat was gone. Mine would still shut off though. I thought Princeton products were quality but now I know. I just got it yesterday so I'll try returning it to the store. It's a shame because it is a very light, small and easy unit to use. Would be a great design if it worked. I'll stick with my energizers.

Update: 4/4/11

Dick's took it back and were unaware of the issues with it.

Update 6/6/12: New packaging has been changed to read 2hrs on high. The packaging I bought it in said 80hrs on high. Not sure if PT upgraded the light at all.

The other reviewers are right. The battery drains while it is off. Waste of money and batteries. Not worth returning it. I put the effort into this review instead.;-)

This is my active headlamp at this point, but after owning several others, I have been disappointed in this one and will be replacing it soon. The lamp is sturdy, compact and lights well, however, at least with rechargable batteries, its performance is sub-par. With my low cost charger, the batteries sometimes would not last more than a few minutes. I purchased a better charger-one that conditions each battery individually, and now will get from a few hours to perhaps 10 hours of run time. I suspect that since it only uses 2 cells and it has a feature to boost light output as voltage falls, it has as rather high voltage cutout for rechargeable NiMH or NiCD cells. I feel it is foolish not to design these flashlights for rechargeable batteries. It would be better to let the light level fall with voltage and still have usable light than a few hours of light followed by a fast blinking but very dim LED once the voltage is low.

My Byte also kills batteries when off - same designer as the Apex?
A reviewer on the REI site reported measuring a 0.5 ma drain for the Byte when off.
