Question: Does the dock charge it directly or must a plug be inserted into flashlight case?
Document: Good quality crafted flashlight from Inova that is bright and has multi-featured button; high, med, low, and strobe. Charge it however many times you want without affecting the battery. 6 years old and still going strong!
I have had 2 T4's fail on me. These lights are bright and have a decent throw. It worked great for spotting and reading spray-painted station markers (even in white) on jersey wall from about 50' away. The battery life was good as well. I could use the flashlight all night (not continuously, of course) without having to charge it.
About 4 mo.s ago upon receiving the T4 from this vendor (sword demon), I noticed the item had been used. I didn't mind so long as the flashlight worked and continued to work for a long time. A week ago I began to have problems with getting it to charge. Now it will not charge at all. I've tried a new charger and a new battery without any improvements. I have tried contacting vendor, and in five days I have not gotten a reply.
The replacement t4's switch shorted out after 3 months and no drops later. (I was more careful with this one). It turns out that fancy aircraft alloy case can't protect the inferior components inside. I expected more from a $100+ light.After a ton of research into rechargeable led lights, I recently bought a pelican 7060 (initially my second choice).
As a police officer I rely on my equipment to save my life. None of us are nice to our equipment so when a cop gives an assessment of a product, it is from a worse case/best case scenario. The following review is based on real world application in a profession that does not forgive.Emmisive Energy Corp: Inova T4.Purchased on April 11, 2009Cost $[...]This light outperforms expectation in an urban environment. Battery life is exceptional along with the charging time.
The light was junk didn't work. It would not charge. Thumbs down on this light.
Absolutely beautiful craftsmanship,you can feel.Beam spread is precise.Charge indicator is a big plus.Dual charging adaptors:110v-12v are another perk...Kevin
Inova offered to take the light, battery and charging cradle back. The charge would then be $39.95 for a replacement.As an update, after speaking with Laurie with Emmisive Energy Corp, they have agreed to replace the light at no cost.
A great light. It can go a good while in between charges. It is so bright that you can not look directly at the bulb when lit. It does a good job of lighting up the darkness as well. It's compact shape and weight are perfect and it is the perfect size to fit in a sap pocket. The head of the light protrudes out of the sap pocket perfectly so no other holder is needed. Good duty light.
For me, that was the majority of the times. But the T4 remains incredibly bright throughout a charge period. The central light cone emmanating from a single LED is intense and is surrounded by a broader halo - perfect! Recently my neighbor needed nighttime help and brought out her huge Maglight that was so dim it was almost useless. I said, "Here, try mine" and handed her the little T4 - she was an instant convert.
