Streamlight SL-20X and Sl-20X-LED Drop-in LED Conversion – Feeler Thread
Update 21 May 2010
Below you can see the picture - sorry for the poor quality image, but you get the idea.
From the top:
- Boost driver board (not yet populated with parts )
- LED board (parts on order)
- Proto of the drop in assembly (parts stacked up, not assembled)
The basic idea is that you pull out the existing lamp + reflector assembly, and replace it with this one.
Hi, as some of you know, I am developing an LED Drop-in replacement for the Streamlight SL-20X and SL-20X- LED flashlight. The drop-in is not quite ready, but in order to obtain decent pricing on parts, I need to estimate the volume needed for the first run. I am expecting to ship 20 of these in June 2010.
This is a FEELER THREAD / Interest expression thread. This means that you are not committing to buy, nor am I committed to sell them.
As a practical matter, this is the kind of light that is most commonly used in public safety / police work, and the design of this drop-in is focused on the needs of that market.
In particular, this drop in will provide:
- High light quality, not just brightness.
- The LEDs are very high CRI, 4000 K LEDs, which give provide high detail contrast. This is somewhat of a new experience for traditional LED flashlight users (like me) that had trouble seeing details, even with a lot more total lumens out the front of their flashlight. This compares to approx. 3000K from the incan bulb assy and a similar CRI. The beam will appear slightly whiter, more like an overdriven incan bulb.
- As much as possible, made in North America and the EU.
- LED power – 12 – 15 watts of LED lighting power, approximately 2X the out the front lumens of the standard incan bulb assy.
- Similar run time to the standard incan bulbs that come from Streamlight, just more light
- As close as possible similar operation and characteristics to the light – on / off
Beamshots and pictures. Yes, I should post some, but I am going through another rev of the build and I want to only post accurate information.
For those not familiar with this family of lights, of course the best information comes from the Streamlight web site, but a quick summary:
SL-20X – Aluminum body, full size flashlight, 5 series, ˝ D size, NiCad battery pack, 10 – 12 watt incan bulb / reflector assy. (I have 3 of these lights myself)
SL-20XP – same, but the body is molded plastic instead of aluminum
SL-20X-LED Aluminum body, full size flashlight, 5 series, sub C NiCad battery pack, 10 – 12 watt incan bulb main beam, plus a 3 each, 5mm LED secondary / low beam (I have 1 of these lights so far)
SL-20XP-LED – Same as the SL-20X-LED, but the body is molded plastic instead of aluminum
All of these are Streamlight factory specified at nominally:
- 200 lumens
- 20 – 25,000 Lux at the VERY CENTER of the beam. It drops off very fast to much lower numbers, but it is a solid thrower.
This drop-ins will only work with the aluminum body lights, not the plastic body lights. The basic reason is that the heat from the LEDs needs to be dissipated by the body, so it has to be aluminum to work.
In case you don’t know about it, you can already buy via Amazon, a drop-in from Terralux that provides 3 watts of LED lighting power, vs 12 – 15 on this one. I think Terralux sells these for around $ 40 – 50 / each. My perception is that they are a bit fragile for my taste, but they might be a good choice on a tight budget.
- Estimated pricing $ 125 / each
- Most likely I will discount the price 10% for those purchased in the first batch compared to future buyers.
- I have not yet decided on payment methods and deposits, but I prefer to keep things simple.
- First batch – 20 to ship in June
- Shipping locations – I don’t think these are so common outside of North America, so I am initially focused on sales in North America. (Canada / US / Mexico) Feel free to let me know if this is an error.
- Please note if you are interested in the one for the SL-20x, or the SL-20x-led, as they are not interchangeable.
So, if you have read all of this, and are still interested, please post here. If these are commonly used by your department, please send an email to me directly. (sales at wirlnet dot com)
Thank you for your interest and patience.
