    Super bright single-LED red, and blue flashlights?

    I'm putting together a lighting effect for an arts show. In the past I've used red and blue lasers. But this new show will run for a month and I can't be there all the time. Lasers are a hazard. They likely wouldn't last a month anyway! So I'm looking for alternatives - powerful red and blue...

    Bright single LED flashlight?

    Thanks hugely! That should get me started. :twothumbs If anyone knows of where to source these items in the UK (postage from the US is going to be slow this time of year) it would be much appreciated. Cheers!

    Bright single LED flashlight?

    Hi, I need a bright tight beam for a particular pupose (a foot diameter at 15ft away). A figure a bright torch could do it. What's out there that's really bright and wouldn't cost too much? Something with an adjustable beam would be great. Cheers!

    Best power supply for running two 10W LEDs?

    Hi, Can I run 2 10W LEDs off one 20W driver? Would that be a constant current driver? Any advice on which to get? I'll be running from 230V mains, so a unit that powers from that would be ideal. Cheers! :thumbsup:

    Is aliexpress any good as a vendor?

    Thanks folks. I'll order a couple as tests and see how they work before ordering more. Fortunately the final assembly doesn't have to be up till November, which gives me plenty of time to get this right. :thumbsup: A quick question: 2 10W LEDs - can I run them off one 20W driver? Is that a...

    Is aliexpress any good as a vendor?

    I'm thinking of buying 10W Red, Green, and Blue LEDs as replacements for the 3W white Cree ZL LED in a number of fixtures. I found this - https://www.aliexpress.com/item/1-PCS-CREE-XML2-LED-XM-L2-T6-U2-10W-WHITE-Neutral-White-Warm-White-High/32407343328.html Is aliexpress a decent vendor? Or...

    Looking for 10W red green and blue replacements for Cree ZL LED

    Hi, :) I'm modifying several Chauvet pinspot lights to go from 3W white to 10W red, green, and blue (separate lamps, not one rgb lamp). This is for an arts installation and I want to use this model of light because of its particular lens optics. (cheap too!) The lamp currently has a 3W Cree ZL...

    Hi, I'd be very grateful for some advice. :) I'm making an effect for an arts installation. I want to use the brightest red and blue LEDs practicable. These can be single(!) or more likely two small red and blue clusters - they will need to foused via a lens to small spot (but that's another...
