DealExtreme P7 HA-III Bike Light
Now I hope the other Moles don’t think I’m stealing anybody’s thunder here, but in advance of the long awaited night light test, planned for one dark evening in September, I just wanted to scribe a few words about this wee beauty – the DealExtreme HA-III P7 LED Bike Light

And here’s some further reading from the light fetishists on the candlepower forum, umm what an interesting bunch of people they sound!

Like a number of us, I have a rather unhealthy interest in lighting that, until recently, I thought I had under control. Already sporting a 900+ lumen iBlaast for the bars and my homebrew set up for my bonce, I really didn’t need anything else. But then ‘Head of New Product Research’ DaveC alerted us to the new DealExtreme bike light.

I was feeling a little low at the time of his email and before I knew it, I’d embarked on some retail therapy and a few days later, it arrived from Hong Kong.

I’ve only used it a couple of times so can’t comment on long term reliability (though LED’s as opposed to HID’s are generally highly robust and it seems very well made), but I must declare the Night Light Arms Race has to be over.

For £50 delivered, you really cannot do better. Its chuffin bright (a claimed 900 lumens) and nicely coloured, the beam spread is excellent, it has 3 modes with a three hour burn time on Hi, mounts easily and securely and comes with everything you need – that’s light, batteries, charger, mounts, the lot. Not a strip of solder or zipties in sight.

Whilst homebrew stuff is fun, there’s the time factor and the way in which the cost always escalates to double your estimates. If homebrew isn’t your thang, at £50 this seriously undercuts anything else on offer and performance-wise, it sits at well over the £200 retail mark imho.

You may be tempted to wait until our lights test but I’d advise you get in quick and snap one up before the Autumn rush sees them run out of stock. The only drawback is the charger is a twin flat pin affair, so an adaptor is needed.

    My McAfee is blocking a trojan download when I use the dealextreme site, so be careful people.

  2. James says:

    I have just placed an order after my first night ride with the moles, the wet one! I will now be able to see a little better!

    It seemed to do the job although you didn’t see the badger!!

  3. Colin says:

    Being disposed to a bit of tinkering, I’ve pulled mine apart, and the shortcomings highlighted by the fella on the candlepower forum are correct (see new link at top of post).

    The mounting screw is woefully short and the amount of material behind the LED is not generous leading potentially to inadequate heat sinking (only an issue I rec if you leave it on high whilst stationery).

    I’ll sort out the screw and do the mods with thermal epoxy and thermal paste to aid heat transfer. Finally, a bit of silicon sealant to stop water ingress where the wire enters the body and it should now be a reliable and cheap, high performance set up.

    Mine didn’t quite last 3 hours on its first outing. Switched off suddenly after about 2.5 hours, so make sure you get an extra batt. pack or have a spare light.

  8. tim says:

    Had a few problems with mine, the glass was broken on delivery. I have spare lens now if anyone needs any. The charger didn’t work, luckily I have an RC Plane charger that charges LIPO batteries. I have purchsed a higher quaklity battery from and will see if I get better runtime etc.

  9. Hi, I have a the DealExtreme HA-III P7 LED Bike Light with a broken glass. Any ideas where I can get some from.

    Dealextreme seems to sell every size except 38.85mm

  10. tim says:

    i bought 4 lens by mistake – if you need 1 let me know,

  11. Thanks for the offer, and thanks for the link.

    Strange I thought that I had looked everywhere on the Dealextreme site. Obviously not though!!
