Simon. I recently bought a L6-GTFC-40. I have to tell you it is an awesome light. DefinitelyOne of my favorites. I do want to ask you if you ever considered a 21700 conversion kit. When I bought my light I bought two of the 26800 expansion pieces from your store. With the spacer added and two of your flat top to button top boards my light runs well off two 21700s. I did have to use cardboard as a spacer to keep the batteries from rattling around but it works great. I figured I would suggest it since 21700 cells are popular right now and cheaper than 26650s.

Is there an OP reflector available that fits the L2?

Can an Osram W1 Red be driven with an 8×7135 biscotti driver? I got an RGB C8+ set and it bugs me that the red has a different UI. I’m considering swapping in a spare biscotti driver I have but I don’t want to burn out the LED or anything.

These are about as durable as the white emitters but they derate a little with heat. Datasheet rates 2.5A max with 3.3A pulse, plots look good like the white so it should be fine as long as you keep it in normal thermal cutoffs (80°C is a killer at 2.5A but…). Actually pretty impressive for a color emitter. That said, I don’t know how much is to be gained above 2.5A but it shouldn’t hurt it at all…8×7135 is usually around 2.7-2.8 anyway with the 350mA chips and didn’t increase much with the 380mA.

Datasheet here: https://dammedia.osram.info/media/resource/hires/osram-dam-5961110/KR%20...

Awesome! Thanks so much Correlux!

Edit: I just opened up the light and I see this 4R7 thing and some red glue looking stuff. Is that a buck converter and potting compound perhaps? I don’t see the same component or glue on my 5A linear drivers in my Green and Blue C8+‘s. If so, then switching to a 7135×8 driver should produce significantly more heat, right?

It’s an inductor…not sure about the driver particulars there and Simon’s product pages are invisible for awhile yet. The coating is not potting compound…it’s a “conformal coating” which is kind of like solder mask, just used to help protect against oxidation and dust, potential shorts, etc. It’s a nice professional touch although the way they often do it with cheap electronics is kinda half-arsed and at times doesn’t make logical sense, but…better than nothing (until you want to desolder things). The 7135 will usually run warmer until voltage drops…they do their job but not efficiently.

It’ll work, but doesn’t run very well. It operates at a higher VF so you’ll get less efficiency. You lose 40% output very quickly. Stick with what’s in it

This is with the 8*7135 biscotti driver. Used this in my first lot of stock when I first started using the Osram red. I stopped after running this test.

Simon, thank you for producing these colorfu C8+‘s! They are delightful, especially with diffusers.

This must be one of the most beautiful beam shots Ive ever seen. Your use of a wall corner to mix 90 degree beam and color convergence was brilliant. If its a Photoshop, it certainly fooled me. Well done!

Thank you! I’m quite proud of how that turned out. The only editing was cropping it into a square, haha.

Hi, Simon, I hope you’re enjoying your holidays! Any plans for s21d with clear narrow optics? And what about putting 519a in?

I like this idea, but I would prefer narrow frosted optics.
Also, I would settle for an S12 with 519A’s.

Simon, any chance you would stock 519A in 5000K (or other temperatures) in the future? 

Some modders reported very good results slicing the 519A, which has the side effect of lowering the temperature. Thus, to start with a 5000K emitter should give an end result of about 4500K, which is desirable for many.

If the 519As become available in the S2+ (and other lights) in a range of colour temperatures from 2700k to 6500k, I can see myself buying quite a few for night photography (replacing my LH351Ds).

Since we’re talking about our hopes for the 519A…(as long as 519A has the similar brightness and better tint than LH351D )

I’m hoping for S21D 519A 3500k Thumbs Up

Sign me up, I had one with 219Bs in my cart before Simon pulled em out.

Also – 519A emitters in S2+ hosts please. A shorty S2+ with a 519A is a tantalizing idea.

Here for the budget torches, HiCRI only except for funlights.

Simon, I hope that in the future each new batch of emitters can go through some standard test procedure for color quality. It’d be a cut above what anyone else does and surely boost sales and confidence in your inventory.

I’m on the fence about getting an M21B with the Getian. Not knowing the duv values for each cct makes it impossible to choose and so I don’t make the purchase.

I have an old Trustfire C10 with 4000k MTG2 and I think an M21B with FC40 will finally dethrone it. But not if it’s at all green.

I’ll be less busy in a few days and I’ll post the test data.

Simon, did you ever get a round to do some measurements? If not, I’m assuming you’re enjoying a well deserved vacation Wink

+1

Would love to have a high CRI alternative to the LH351D in various temperatures. Already have too many LH351Ds and I’m done with SST-20, which is too narrow beam and only 2700 and 4000K (low CRI of colder ones is a no go).

I remember when Simon released the driver first red W1 Osram, and iirc it was made more so for the lower voltage frequency of that LED not necessarily the low amps. 

Couldn't a red W2 be used with 8*7135 more efficiently? I have used a couple, but I've never looked up what they're Vf is.
