Decided to go with a 405nm build using a PHR diode. Does anyone know if This would be a suitable drivers?
Or are there any better drivers that aren't too expensive that I could use?
Thanks

Edit: I've used the search bar below but wasn't able to find any answers

I don't think so. The site says it's for red and near-ir diodes. Your best bet is a boost driver, but finding one may be difficult.

If you haven't ordered yet, get the diode/driver combo from DTR.

Or hunt down an X-boost or microboost, as both have been hard to get lately.

I don't know the answer to that as I am unfamiliar with the PHR 405nm diode, but I wanted to point out before you run into a problem that if your still planning on using a C6 then you must spend the extra dollar for the drilled pill if you use one of those rectangular drivers, with the regular pill there wont be enough room unless you use a round driver, or maybe you could drill the pill yourself. With the non drilled pill that host barely has room for your wires and you have to remove the rear part of the module. Other than that it is a very good host and easy to work with. When your done and ready to screw it together just be sure to assemble the parts carefully without twisting your wires or you will break something, its a common first mistake.

I've seen that combo but I'm looking to make a cheaper build which is why I decided in using the PHR, I haven't built one before so I don't want to waste money on an expensive diode and driver.
Are there any driver alternatives I can use that would fit into a 12mm x 30mm module?
Would a linear driver be suitable?

I've decided on using a custom host as it would mean I would have a unique first build.

Technically, yes a linear will work, but it may not with just 2 batteries. 405nm diodes have a high voltage drop, typically 6V+. With a linear driver dropping 1 - 2V, theres barely any left for the diode. That's with fully charged batts.

So a linear would work but is not advised?

What would be a good driver option that isn't too expensive (around $5-$10)?

That one has problems with low power diodes like the
PHR. I've seen it blow diodes under 200mA for no
reason. Violet diodes are particularly sensitive. I
would avoid it like the plague.

Linear is fine, but keep in mind these diode drop
around 6V, so you need 2 lithium cells in series with a
linear or buck driver. A buck/boost or boost driver will
work fine. I would go with a boost driver like the Micro
Boost just because of the higher voltage. PHR like to
run at around 110-120mA.

Oh okay, thanks for the warning. I wasn't too sure about Aixiz as a driver options as I've seen mixed reviews, but I haven't seen anything about blowing the diode. Okay so my best option would be to go for a boost driver. Would this be a suitable option?
I've been looking at these drivers from Odic Force as they are based in the UK and have good reviews.

That first driver( for 405nm diodes) looks ok from what info the site gives. It's a boost, so it only needs one battery, plus most build with 405nm diodes used boosts. However, I don't think anyone has used it before. To my knowledge.

I'm unfamiliar with the PHR diodes, I've only made builds with the BDR and SO6J.

Make sure you know what the max current of the diode. I woud set it a little below.

Do you have a test load to set the current with? It's risky using the actual LD, especially these senitive 405s.

Yeah I've been told the current to use is around 120mA

Yes I will be using a test load to adjust the current before connecting it to the diode.
Okay so my best option would be to go with the first one?
