Hi,
I recently bought a helmet with a rear strap to attach a rear blinkie. Does anybody did the same with a Cateye LD1100?

Regards.

Its heavy and very directional.
Great on the seatpost!

For helmet the ld100 works well

I wanted to swap my superflash from the helmet to the frame thinking it was too directional. Your opinion is based on direct experience or in guessings?
Best regards.

I run my Cateye TL-LD1000 (older version of the same light) on the seatpost with a Cateye TL-LD500 on the back of the rear rack for backup. I use a Mars 3.0 on the back of my helmet.

The Mars 4.0 that I looked at, was significantly less directional than the SuperFlash. That might be a good, very powerful helmet blinkie to consider.

Hi,
Thanks to all for your answers. I don't want a more directional light, but a less directional one as when you ride your head is not always in the same position. That's why I choosed the Cateye LD1100 for my helmet. Having more than one leds row it will be easily seen from more angles and distance when attached to my helmet. Can anybody confirm this particular through direct experience?

Regards.

The 1100 is considered directional in that it appears brightest when viewed from certain angles; straight from the rear and straight from the sides. The 500, for instance, is not as bright, but it spreads it's light over a wider area; the light appears to not be less bright when viewed from a greater angle. The 500 is also much lighter weight and a CPSC certified reflector.

I suggest the 1100 for your seatpost and a 500 for what I think you might be looking for in a helmet light.

LEDs are generally very directional, it's the optics that surround them that spread the light over a greater angle. i'd suggest the LD100 as suggested above because it's pretty much as close to omnidirectional as you'll get.

having two rows will hardly effect the light spread at all. it's very directional, i've compared it to my mars 3.0 and it's got better intensity and penetration but the same or less spread.

Or the Planet Bike BRT-5, which is far brighter than Cateye's LD500 and is also designed to clip onto stuff without having a super-long clip that'll gouge the rider's neck. And the Mars 4.0 struck me as having an exceptionally large hotspot, it's worth looking at too.

Hi, Mech,
Thanks for your help, but, as I tried to explain, I do already have the Tl LD 1100 and two Superflash. That's why I want to know if I attaching the Cateye to my helmet would be a better idea than attaching the SF regarding leds light directionability and consequent rear motorist visibility.
Thanks again.

I see. If I had those two options, I would use the SuperFlash on the helmet. The LD1100 is relatively large and heavy, its clip is long and would dig into my neck, and I think it is dim when it isn't pointed in the optimal direction. Try aiming both lights upward or downward by 20°, then view them from 20 meters and see which one looks most noticable.

If you want a helmet blinkie, I recommend the planet bike blinkie 3H. Small, light, on a pivot so it always points back.
