 Jet Lites Jet Blast 1000 HID Bike Light Review

From Jack Gresmer, president of NiteRider

“Certainly the new NGX is twice as bright as our LED light. And to me one of the most important features of NGX is the resiliency of it…. The NGX lamp is definitely more efficient than old HID in terms of power consumption per lumen and it does have a little faster start up. Welch Allyn listened to their customers and responded to what the market was looking for.”

“Our relationship with Welch Allyn has been very good. They’ve worked with us on every level…. When it became pretty evident that the LEDs were going to be able to compete with the HIDs we told Welch Allyn that these are the things that you need to do. You need to make the light brighter, you need to make it more resilient, you need a faster startup and it needs to be more efficient. And they responded with all of those things.”  

“I’ve been fortunate enough to be able to use one of our new SlickRock HID lights. I’ve been riding one for a few months now and it’s twice as bright as our brightest LED light…. I’m an avid mountain biker and when you’re in the woods and it is dark you can really never have enough light so I’m a huge fan of HID.”

From Jerry Murphy, Dive Rite product manager 

“The new Sôlarc technology is double the light output of the older HID bulb. It still maintains a similar burn time so we can use the same battery packs; it’s the same small size but twice the brightness…. 100 percent improvement; twice the brightness.”

“We’re using Sôlarc technology in our lights primarily because it’s the leading edge…. Its brightness and its efficiency are far superior. Its reliability is second to none. Welch Allyn’s excellent products make our products look far better.”
