Default Driver for PLTB450B

Yo guys,

Havent been active in lasers for a few years now and would like to get started again.

Im looking for a driver to output ~1A from a single cell.

Preferably a cheap one with a spring attached to it already

So i came across these two:

445 450nm 0 3 1W Laser Diode Drive | eBay

450nm 445nm 473nm Blue Laser Diode Driver 1W 1 4W 3 7 4 2VDC in Power Supply | eBay

Though Im not sure how much they really put out, especially the first one since it doesnt have a pot.

Which one would you prefer and do you have any experience with them ?

Greets,
Machro

Unfortunately the concept of "cheap" and "reliable laser drivers" don't usually go together...

If the listings are correct then both drivers are boost drivers and should work fine with a single cell setup. Although it's your risk, personally I would use a quality boost driver that has been proven reliable. You're going to spend 50 bucks on the diode, why not spend an extra $15 for a good driver?

Hi that's right you get what you pay for . Will is correct 100% lazeerer xdrives are the ultimate drivers out there. PM him and he'll do you no wrong he's one of the best. I never went wrong with his drives. He will make what you need, don't put you diodes in danger.
Trust me you'll be satisfied.
Good luck lase on.. :-))

What do you think about this LED driver ?

http://www.ebay.com/itm/131267889567...%3AMEBIDX%3AIT

Looks pretty good to me since it has an inductor to boost voltage.
Hast modes too ..

That is a LED driver. I see many people using them to turn their laser diodes into LED's. You can get an X-boost from Flaminpyro for the PLTB450B.

Default Re: Driver for PLTB450B

Is there such a big difference between Boost LED an LD drivers when they both output a decent current and boost voltage ?
Or are you just talking about quality issues ?

Led drivers tend to spike when first turned on and can have a lot of current ripples. Leds can take this abuse. Lds cant. Good ld drivers have "soft start".

I asked the seller, he said the driver is not constant current.

However guys, thanks for the help.

Hi M,
Just like DTR said go to flamingpyro or lazereer these guys are the best and will give you what you need without any guess work. You have your diode get the correct drive for the LD. All thes guys here are awesome vendors and been around doing this a long time.why go back and ask the vendor your answers are here at you finger tips. Order that drive bro don't stop now.
Good luck enjoy this great hobby but be safe get some correct glasses :-))
