Customer Reviews

Tek4 5-Watt Flashlight is rated 4.6 out of 5 by 45.
Rated 4 out of 5 by from TEK4 RP4450LK Flashlight: Remarkably Bright! But is it really necessary? I already owned several of the TEK4 RP4400 LED flashlights before purchasing this 5W LED flashlight. I suspect that many folks pondering this purchase are in the same situation. For those folks: do you remember when you purchased your RP4400, brought it home, and compared it side-by-side with the other flashlights in your home? I remember being blown away by how much brighter the RP4400 was than my other flashlights. If you compare the RP4450LK to the RP4400 you'll probably have this same reaction. It's THAT much brighter. Are you looking for something small that you lost in a field at night? Are you trying to penetrate the dark woods at night to see what's out there? Well then, this flashlight will do the job. It's like a big spotlight in a small package that fits in the palm of one hand. Having sad all that, and having owned one of these for more than a year I must now confess that I rarely use it. For nearly every use, I prefer the RP4400. The RP4400 may not be as bright as it's big brother the RP4450LK, but it's still very bright and the smaller size means it's easier to carry or put in a pocket. And at less than half the cost of the RP4450LK, one will be less worried about breaking or losing an RP4400. If you have a need for the brighter light, get the RP4450LK. If you already have an RP4400 and it's good enough for you, stick with it.

Rated 5 out of 5 by from Great Light, Extremely High power I was shocked by how much light this flashlight puts out. I thought at sfirst the price was steep but now i see it is well worth the price. I can shine this light through rough shrubbery while hunting and it is blinding. great job Depot

Rated 4 out of 5 by from Great Flashlight Great flashlight. Have owned for over 1 year and works as well now as when we purchased. Very bright, good size, holds charge very well, beam shines a very long way. I rate it 4 stars as is, but would like to see a option for high/low beam and would like for the on/off button to be easier to find in the dark by being raised or have a different texture. I can overlook these "flaws" because it is a great flashlight. We have purchased as gifts for family members. Would definitely recommend.

Rated 5 out of 5 by from best flashlight I have ever owned At first I thought the price was a little steep, but now I think it is a worthwhile investment. I can carry the flashlight in my pocket, and it is almost as bright as one of my car's headlights. The only drawback is that it can be slightly difficult to find the on/off button in the dark, because the flashlight is round and the button is flush with the shaft.

Rated 5 out of 5 by from 93% customer recommended and 4.5 stars, One of the best rechargable flashlights that used to be availible Bought one several years ago and has been dropped, kicked, dunked, chucked and still works like the day I bought it. Unfortunately the product is not avail any longer. Would love to purchase 10 more if they came back to the market. Charge lasts hours if continual use but weeks/months if only use little each night from my experience walking my dogs and checking out my property after sun goes down. Note to Ryobi/Home Depot - I know this one product isn't going to make tons of money as a hot ticket item but a product with 4.5 stars and 93% + customer satisfaction rate just seems like a product that should be on the market and the few that were lucky enough to get one will agree. Please bring the tek4 flashlight back! :-)

Rated 4 out of 5 by from no other flashlights needed My son bought this light for my father (his pawpaw) for christmas. I suggested he purchase him another rechargeable light just like ones he has previously owned. So happy he did not listen to me, this light is awsome. I have a flashlight which I was happy with until I used this one buying one for myself so I can quit borrowing daddies. Yes the on/off button is a little hard to locate in the dark only problem we have with it. We both use the flashlight daily when walking out in the yard.

Rated 5 out of 5 by from Amazing Brightness and Amazing Battery Life. I have not had this flashlight long, so I cannot claim how good it is longterm. However, it has amazing battery life and is extremely bright and dwarfs all other flashlights I and most people own in brightness.Granted, it is a lot more expensive than most other flashlights however, the build seems solid and assuming it is long lasting and as durable as it seems and the batteries continue to be sold by Ryobi, I expect this flashlight to be the only one I or most people will ever need. My main concern would be how long the special battery lasts and if Ryobi will continue selling them for a long time or not. For anyone concerned about the cost of the batteries, it really is not much more than regular batteries for a flashlight and these last a lot longer and a lot brighter and can be recharged. I highly recommend it.
