This 1500 lumen light from BikeRay offers great run times, low heat & a very effective reflector. As night ride season approaches we run a detailed test.
Introduction
It's always a bit depressing having to get the lights out as the evenings close in. However with modern LED technology, the hassle & cost of night riding, is greatly reduced. As a result we are doing more & more night riding each year.We are testing the £109.95 BikeRay IV 1500 Lumens LED Light. BikeRay have been around for some time now, & offer a range of high output lights. Here are the specs.

BikeRay IV Features & Design
- The light comes in a smart box with clear & easy to understand instructions.
- The inclusion of a head mount & storage bag is welcome.
- The BikeRay's aluminium body is well crafted, with some of the most extensive cooling fins we have seen. They wrap around the body increasing the cooling area like a big heat sink.
- The 4 Cree X-PG's are well positioned in the head, & the reflectors look smooth & well positioned. Overall it all looks tightly put together.
- The X-PG LED's are the same size package as the XP-E, but with a larger die. Therefore the resulting beam has a little more flood. This was evident when running the light.
- The BikeRay IV power /settings button is one the of the most tactile we have used. The little rubber indentations felt great.
- The extension cable means that you can choose the right cable length when either bar or head mounting the lamp.
- The battery looks to be well sealed & there is a reasonable amount rubber around it to protect it from impacts.
- The 6.6AH battery is not very large or heavy allowing it to be mounted in a variety of positions. When bar mounting, it fitted neatly under the front of the top tube.
- The BikeRay IV battery bag has a large Velcro loop & a secondary buckle to keep everything in place.
- Battery Indicator on the lamp is clear & easy to understand & when riding.
- Coming in at well under 500g the light is a very competitive weight.
- The light is only £109.95!
- The Cree X-PG’s aren’t the latest in LED technology, with the newer XM-L & XM-L2 offering slightly better efficiency & output.
"The centre spot is not the brightest but the spread of the light beyond that is superb...."
BikeRay IV In Use
- The BikeRay IV charge time was as advertised. It seems to do a fast charge for the first 2 hours followed by a trickle up to 100%. As a result you get a lot of run time off only a couple hours charge.
- The fin covered housing, does a great job of keeping the lights temperature down. It’s one of the coolest lights we have tested even after being run for a few hours.
- The beam is very much a flood. The centre spot is not the brightest but the spread of the light beyond that is superb. We really liked the optics used on the BikeRay & they seemed to maximise the light generated by the 4 X-PG’s. Scroll to the bottom of the page for beam shots.
- The LED's are slightly tinted with just a hint of yellow. This helps you pick up trail features & is comfortable on the eyes.
- Unlike a lot of other lights, the blink mode is genuinely useful as its not blindingly fast. It’s a sensible speed on the Bikeray, & we used it extensively when getting to the trail head.
- The big backlit button on the rear made it very easy to switch between modes, even when riding. It looked nice too.
- We got 3.8 hours run time rather than the stated 4.5. That’s still excellent to be honest. The X-PG's can produce up to 493 lumens @ 4.9W. So in order to achieve 1500 lumens they would need around 15W. Over 4.4 hours & using a 8.4v battery, that needs a pack with capacity of roughly 8.0AH. That's 1.2AH more than the included pack. That may account for the 3.8 hours run time we got.
- The 3 step fuel gauge was useful & accurate. Each stage seemed to accurately cover about a 1/3 of the battery’s life.
- Without an elaborate test rig, its difficult to say if the Bikeray does pump out 1500 lumens. It uses 4 X-PG R5's which at 1000mA can produce 348-370 lumens each. So on paper it seems accurate. In use, its power seems to fit in between the 1000 & 2000 lumen units we have used.
- Durability so far has been good. The lamp has gotten pretty muddy recently, and after a good wipe down is a good as new.
- The excellent flood, comes at the expense of the lights throw, which is fairly average.
- You will need to supplement the BikeRay IV's flood, with a light on your helmet for fast single-track riding. We always ride with 2 lights anyway.
- Only having one button to cycle through options felt a little restrictive. It meant that sometimes you would activate the strobe, when you just wanted to switch between high & low or vice versa.

Final Thoughts
The BikeRay IV is nicely made, light weight, & keeps cool. Being able to run at full power for over 3.5 hours is impressive & something not offered by many lights at this price. There are a good range of included accessories & the light is very easy to mount & position. In addition the quality of the light output is very good. It doesn't use the latest or greatest LEDs, but what you do end up with is a very broad & effective flood, which is ideal for mounting on the bars.We would have preferred brighter centre to the beam, & you will need a head lamp in addition to the Bikeray, if your riding really fast technical terrain. However you are getting solid light, backed up by a UK company with a 12 month warranty for £109.95! Its definitely worth considering, as the bar option in your lighting set-up.
